Well, one characteristic is the unexpectedness. For example, in a story, you might expect a real monster but then it turns out to be a small, harmless animal doing something silly. Another is the over - reaction of the characters. When they get scared over something that's not really that scary, like a shadow that looks like a demon but is actually just a tree branch, it's both stupid and funny.
A girl was so excited to try a new dance move she saw online. But when she did it, she slipped and landed right in a puddle. She was all muddy but couldn't stop laughing at herself for being so clumsy.
One stupid but funny story is about a man who tried to ride a shopping cart like a skateboard in a supermarket parking lot. He ended up crashing into a trash can. Also, there was a lady who thought she could communicate with her fish by making fish - like noises at the aquarium. Her family just watched in disbelief.
Once there was a man who tried to open a banana from the wrong end for his whole life just because he thought that was the right way. It's so stupid but also quite funny.
One funny stupid scary story is about a guy who thought he saw a ghost in his room. But it was just his white laundry hanging on the chair. He got so scared and ran out of the room only to realize his stupidity later. It's funny because it was such a simple misunderstanding but in the moment it was terrifying for him.
Once, my Sim was trying to cook and ended up setting the kitchen on fire while doing a really goofy dance. It was so stupid but hilarious as the whole family panicked.
There was a time when a girl was home alone and heard strange noises. She got really scared. Turns out it was her cat knocking over a stack of cans in the pantry. The cat had a silly look on its face when she found it. It was both stupid and funny in the end.
Sure. Once there was a man who thought his remote control could open his front door. So he stood there for ages, pressing buttons, until his neighbor came out and asked what he was doing. Another one is about a guy who tried to take a selfie with a wild deer. He got too close and the deer chased him all around the park.
There was a guy who tried to steal a bike that was chained to a pole. Instead of using bolt cutters or any proper tool, he tried to pull it apart with his bare hands for hours. Eventually, he was caught red - handed when the owner came back. It was so stupid because he could have easily been seen and he didn't even have a proper plan for stealing.
Sure. One time, my friend thought that a toaster was a phone charger. He tried to plug his phone into it. Another one is about a guy who put salt in his coffee instead of sugar just because the containers looked similar. And there was this person who tried to open a car door with their house key for a good five minutes before realizing it was the wrong key.
