One player created an elven ranger who was allergic to nature. So, whenever he was in the forest, instead of being in his element, he would start sneezing and getting rashes. His attempts to complete ranger - like tasks while constantly being affected by his 'allergy' made for some very humorous role - playing.
There was a human fighter who thought he was a master swordsman. But his sword was actually a prop sword that he got from a theater. He didn't realize it until he went into his first real battle. He was swinging it around like a madman, and when it broke on the first hit, his look of shock was priceless. His journey to find a real weapon while still maintaining his 'master swordsman' ego provided lots of laughs.
Sure. There was this one time a druid in a group thought he could transform into a huge bear to intimidate a group of bandits. But he accidentally turned into a small, fluffy bunny instead. The bandits were so confused at first, and then they started laughing. The druid was so embarrassed but it made for a really funny moment.
I heard of a paladin who was very strict about following the code of honor. But during a tavern brawl, he accidentally punched a barrel of ale instead of the thug he was aiming for. The ale sprayed everywhere, drenching the whole party and making them smell like a brewery for days. It was a mess but also really funny.
Once, a friend created a character who was a gnome bard. He was supposed to be a great singer but in his backstory, every time he sang, small animals would run away in terror. It made for some hilarious role - playing moments when he tried to perform in taverns.
I heard about a hamster that somehow got into a box of cotton balls. It made itself a little cotton ball nest right in the middle of the box. When its owner found it, it peeked out from all the white fluff, looking like a little furry snowball. That was such a comical sight.
There was a Doberman that loved to play dress - up. Its owner would put silly hats on it and take pictures. One time, the Doberman got hold of a tutu and ran around the yard wearing it, looking both proud and very funny. This Doberman also liked to pose for the camera whenever it had its 'costume' on, which was really cute and funny.
I heard about a wedding where the ring bearer, who was a little boy, decided to take a nap right in the middle of the ceremony. He lay down on the aisle with the ring pillow under his head. It was hilarious. The pastor just had to step over him to continue with the service.
I heard about a bachelor party where the groom - to - be was so drunk that he mistook the bride's father for a cab driver and tried to give him money to take him home. The father just played along for a while before revealing who he was. It was quite a comical situation.
Well, I heard of a stoner who tried to put on his shoes but put them on the wrong feet and then walked around like that for hours without realizing it. He wondered why his feet felt so strange.
There was a man at a bar who got drunk and thought the bar stool was a horse. He was trying to ride it around the bar area, shouting 'giddy up' and all. It was quite a sight. The bartender just watched in amusement. This went on for a while until he finally passed out on the 'horse'.
Well, I heard about a person with amnesia who thought they were on a spaceship. They started looking for controls to pilot the 'ship' around their living room. They were making beeping sounds as if they were communicating with an alien base. It was a very comical sight.
