We all have lapses in our knowledge, whether it’s not keeping up with current events or not being the best spellers. But some people really let the world pass them by without taking in any knowledge that could help them out. These people have gone well beyond pulling on a door that says push, and others have been around to catch them in the act of being absentminded.

Even though some of these people have lost jobs, friendships and opportunities because of their brainless actions, they didn’t even realize that they were the daft ones in the situation. Maybe they’ll get a clue after their clever friends catch on to their dumb ways!

She is Untrainable

Unsplash

We hired a girl a couple of years ago. I told her where the manager’s office was during her first day on the job. On her second day, she asked me where the manager’s office was again, so I walked her to the door. On the third day, she asked me where it was yet again.

At this point, it was pretty obvious that something was wrong. Our manager chewed out the girl who trained our new recruit for not teaching her the job properly. In response, the trainer pulled out her phone and showed the manager a picture of the new girl wearing the uniform backwards, saying,

“Look at this. This is untrainable.” The new girl got fired about three weeks later for stealing the product: she thought she just got it for free whenever she wanted as an employee.

She's Not Sure What Her Boyfriend's Name is

I worked with this girl last summer who was beyond dumb. At first it was amusing, but then it just got really sad. We were talking about Nelson Mandela being really sick and she said, “Well I sure hope she’ll be ok, her music is so good!”

She also struggled to answer when asked what her boyfriend’s name was. Which, when we found out his name, was incredible. She said, “I can’t really pronounce it, so I just call him Mike. He spells it like M I C H A E L.”

I knew a guy who injected himself with peanut oil, hoping to slow the flow of blood to his brain and keep himself in a constant state of “high.” He’s dead now. Not from the peanut oil, but from an overdose a few years later. I guess some of us could have seen that one coming…

Have You Ever Seen a Clock?

I was working retail at the time, and this lady walked in and asked me to tell her when it was a quarter after 10 AM, as she needed to catch a bus. We were slow, so I obliged. 10:15 rolled around and I told her, so she dropped her stuff and ran out to get to the bus.

Five minutes later, she comes back in scowling. She then lectures me on how to tell time. “How much is a quarter? 25 cents! So why would you tell me a quarter after 10:00 is 10:15?? It’s 10:25!!”

Both an Idiot and a Jerk

Unsplash

I worked very briefly with a woman who showed herself to be both an idiot and a jerk. Her grandmother died and she and her relatives discovered that the man she’d known as her step-grandfather had never even been married to her grandmother.

She bragged about the family kicking him out of the only home he’d known for three decades because, “If he wasn’t good enough for my grandma to marry, he’s not good enough for us.”

He was an elderly man who lived as this woman’s husband and had everything taken from him out of pettiness and spite. It showed me how stupid she was, and I was right. She was fired a week later.

He Could Just Look it Up

There was a guy who wound up wanting to fight me because I was explaining to him that “calamari” was Italian for “squid.” He insisted that people do not ever, ever eat squid.

This man also insisted that all zebras in Africa are extinct, despite my ability to show him photographic evidence to the contrary. Despite his ability to look it up.

Dumb Ones Have All the Luck

Unsplash

I had a roommate who was about 6 months late on rent. It’s a 10 month lease and we’re in month 8. They’re threatening to sue us. He got a tuition refund. $700. (2 months rent). He goes to play poker with it, despite our constant pleas not too. DOUBLES UP.

He shows us the $1,400 (because he’s dumb like that). This is Saturday night. Office is closed Sunday. I go to work Saturday night, and then work a long shift Sunday, feeling good. Monday after classes, he comes in. First question, “did you pay the rent?” 

Bumbling stumbling excuses, “I paid off some credit card balances and some other money I owed my parents.” “So how much did you give the complex?” “None.”

Blew my lid, almost punched him right then and there. I will bet every penny to my name that he went back to the tables Sunday night and lost it all. Somehow he came up with the money though…

He's a Belieber

Unsplash

My ex roommate’s boyfriend. He was 22, he actually idolized Bieber, One Direction, etc., and did everything he could to be like them. He was also homophobic, probably gay because he often wore his girlfriend’s clothes from Forever 21, and refused to get a job because “the band is totally gonna make it!”

He also pushed his girlfriend down a set of stairs, and was so in love with himself that he took mirror selfies, posted them on his Facebook, then sent them to his Facebook page that he made for himself.

Absolutely the worst person I’ve ever met. To make sure he didn’t come to the house, I actually convinced him that our building was built on an ancient Indian burial ground, and that strange things did happen from time to time. He never came back.

Let's Agree to Disagree

Back in high school, a guy named Kevin was arguing with me, and anyone who would listen, saying that STDs are prevented by having intercourse.

After about a minute of explaining to him what the word STD meant, I decided to just say, “let’s agree to disagree” so I could finally move on with my day, even though he couldn’t have been more wrong.

But he didn’t let it go. He pulled out a $50 bill from his wallet and bet me that he was right. After he looked it up, the crowd mentality forced him to pay up. Smart move there, kid!

My Car Runs of Gas

My friend Sara and I were once driving around in her car (in the late nineties), and her car battery died. We were only a mile away from my house, so I walked there, grabbed my car, and headed back. I parked and lifted her hood.

She asked what I was doing. I told her that I was going to connect the jumpers, because her battery had died. This girl looked right at me and said, “My car runs on gas, not batteries!”

She Doesn't Have Any Kids... That She Knows Of

One time, my now ex-girlfriend was watching Maury Povich. It was one of those paternity test episodes with the classic “You are NOT the father!” moment.

"Face" the Store

Unsplash

I was working at a grocery store over a decade ago. This one kid was new and the manager asked him to “face” the store when he asked what he could do.

“Facing” in this context means you make sure that the aisles look nice and neat, and that the product is pulled forward and visibly facing you as you walk down the aisle.

The kid couldn’t be found until someone told the manager that one of the workers was just standing out in the parking lot, facing the store. I will never forget that!

A guy I know had just purchased a new, high-powered BB gun. We had just finished shooting it in the backyard when he decides to point the barrel right at my face and pull the trigger several times. I tell him to stop being an idiot.

I live in southern Spain. I once met a girl from the USA who was here on some kind of exchange program. When I asked her how she liked Spain so far, she said, “I’m loving it. I just don’t know why the plane took so long to get here. I mean, we are just a bit BELOW MEXICO! I don’t know why the flight was so long!”

Then I told her that we were in Europe. She didn’t believe me. Her reply was “Europe? It can’t be! Everyone here speaks Spanish, so we must be somewhere near Mexico for sure!” She was in university. I still don’t know how or why…

Which is the Bad One?

My college roommate was, without a doubt, the dumbest person I have ever met. She was writing a paper about segregation and could not grasp how “separate but equal” was a bad thing despite two people trying their darndest to explain it to her.

After nearly half an hour, my other roommate and I just gave up and left the room. I still wonder how she passed that class. And she once asked what the difference between legal and illegal was. She wanted to know “which was the bad one.” This girl now teaches elementary school. Her poor students.

Thanks For Nothing

I asked a temp at work to weigh a couple of lever arch files for postage. She came back and told me that they were 65 kg. I asked if it were possible that it was 6.5 kg, but she insisted that it wasn’t. We argued about it for a good 5 minutes.

It wasn’t until I asked her how much she weighed (59 kg) that it finally twigged in her mind that these two small folders couldn’t possibly weigh more than her. Thanks for nothing, Karen.

Foreign Relations

I was working at a French company. We were working with a development team in Vietnam on some IT project at one point. The project manager they report to in HQ was French. They didn’t like him, and he knew it.

The Vietnamese team did some great job, and he wanted to find the correct words to congratulate them, hoping to smooth over their future relationship. He sent an awful “thank you” email: 

“When we see the quality of your work, we can only realize how sad it is that we lost you guys as a colony!” The French expats in the Vietnam office told me they were hiding in shame for a full week after that…

My friend legitimately had no idea that fish, the food, came from actual living fish, the animal. She decided that she wasn’t going to eat it anymore when she found out.

After that apparently traumatic incident, she would text me at all hours of the day and night, asking if whatever food she was about to eat was from an animal or not. I literally had to coach this grown woman on what meat products come from what animals. She still doesn’t believe that tofu isn’t from an animal.

He Couldn't Figure Out How to Do Anything

Unsplash

I used to work with the nicest person I’ve ever met, but he was also the dumbest. Even though he had been at our restaurant for over a year, he still couldn’t do anything successfully besides washing dishes without someone watching over him. He just could not figure out how to do anything on his own.

Someone (usually me) would have to watch over every little thing that he did to make sure that he was doing it right. It would have been frustrating if he wasn’t the nicest darn person on earth. He was always so happy to see you and did everything with a smile on his face.

Luckily, he could wash dishes like an absolute beast. I’m not exaggerating when I say that he could wash dishes faster and more effectively than anyone I have ever met.

In fact, that’s why he was often asked to do other stuff: he was always finished his regular workload extremely fast. His wife was normal and all of his kids became doctors or engineers. They were all crazy smart. And he was sooooo darn nice!

Who's to Say?

I remember proofreading a paper for a freshman student who my roommate happened to have a big crush on. It was on Jonathan Swift’s A Modest Proposal, but somehow this freshman didn’t seem to understand that it was satire, which would have probably been explained in lecture.

The opening lines of the paper are burned into my memory. “Eating children would not be a good thing to do. In fact, we could even say that it would be bad.”

Petrified Trees Come From Food Preservatives

Unsplash

My old roommate’s boyfriend. He spent the better portion of dinner/movie stating how food has too much preservatives in it now, and that’s why there are trees that have been petrified. Petrified trees, because of preservatives in food.

Also, you can’t eat “Bucky Balls” (or any magnet in general) because your body works off of electrical currents, and if you ate a magnet, it could disrupt them.

She was also pretty dumb, spent an entire night sobbing about being pregnant, gets an abortion, and then makes a point to call out people on Facebook for discussing the topic, saying things like, “I could never do that to an unborn child, every child is a gift. Nope, I don’t miss either of them, not even a little bit.

How Did She Get the Job in the First Place?

When I was 19, I waited tables with a girl who didn’t know how to tell time. She was 18, fresh out of high school. Now, she wasn’t like mentally challenged or anything, she was just really, really dumb. She also went to the kitchen and asked the cooks how to roll a joint.

She explained that she had all the stuff, but couldn’t roll it. Our boss was RIGHT behind, and had to have heard her. The cooks told her to shut up. She did stuff like that all the time, and she sat people at the wrong tables, messed up orders, and forgot her schedule, and would be late/miss shifts a lot.

Gravity Doesn't Exist

One girl in high school, let’s call her “Lisa,” honestly thought that gravity didn’t exist and the reason why we didn’t just float away was because of our weight.

Took about ten minutes to explain that gravity gave us our weight. She then proceeded to ask if gravity could, in her words, “Break like a pencil.” After explaining this impossibility, she finally stopped talking.
