Sure. In a tennis match, a player's racket suddenly turned into a giant fly swatter. Every time the opponent hit the ball, the player with the fly swatter - like racket would just swat the ball away in the most comical fashion, making the ball fly into the stands and hitting the spectators' ice creams.
Imagine a hockey game where the puck was actually a small, live mouse. The players were skating around trying to catch the mouse - puck. One player accidentally tripped over his own skates while chasing the mouse and landed face - first into the ice. Another player finally caught the mouse - puck but then felt so sorry for it that he let it go free outside the rink. It was a really silly and funny scenario that could never happen in a real hockey game.
One funny fake sports story could be that in a baseball game, the pitcher threw a ball so fast that it actually went through the catcher's mitt and straight into the concession stand, hitting a popcorn machine and covering the whole area in popcorn. The umpire declared it a 'popcorn out' and the game continued with everyone covered in popcorn.
There was a baseball game where a player ran so fast to catch a fly ball that his cap flew off. But the wind blew the cap right into the path of the ball, and the ball landed on the cap. It was really a hilarious moment.
Once in a baseball game, the pitcher got distracted by a flying seagull. He ended up throwing the ball in a completely wrong direction, right over the catcher's head and into the crowd. It was a very funny moment in that rather serious game.
In a soccer match, there was a timeout because a dog ran onto the field. The dog started chasing the ball and the players were just standing there amused. It took a while for the officials to catch the dog and resume the game.
Sure. There was a football match where the goalkeeper got distracted by a butterfly. As the ball came towards him, instead of catching it, he chased the butterfly. The whole stadium burst into laughter.
At a community sports day, there was a three - legged race. A pair of friends who were really competitive accidentally tied their legs to the wrong partners. They started running and immediately realized their mistake but still tried to continue, resulting in a comical tangle of limbs and a lot of giggles from the spectators.
In Finland, there's this strange sport called wife - carrying. A man has to carry his 'wife' (it can be his real wife or just a female partner) through an obstacle course. It originated from an old legend and now it has become a popular and very humorous event. The most interesting part is seeing the different ways people carry their partners. Some use piggy - back, some use a fireman's carry.
In a football game, a player was so excited after scoring a touchdown that he started doing a wild victory dance. But he accidentally tripped over his own feet and landed face - first on the grass.

There was this girl who used a fake ID to buy alcohol. She thought she was being super sneaky but accidentally used a picture from when she was 12 years old. The cashier just looked at her and started laughing out loud. It was really embarrassing for her but also quite funny in retrospect.
Well, here's a story. In a fake war, a battalion of soldiers decided to have a 'cooking competition' instead of fighting.
