okay, both of these stories are from the game i used to run at GenCon every year (if you're bored look in old prereg books under 2e D&D Mafia Mania).
1) so pyro-klepto, the gnomish-thief (who is immune to fire - lucky him) gets separated from the rest of the party on his own dungeon level. the dungeon room he's in is sort of like a gameroom. he starts playing with one of those claw machine things and gets a few tiny magic items. eventually, however, gets a live chicken. being a hungry gnome, he is determined to eat it. so he starts chasing it around trying to attack it (and keeps missing).
annoyed, he goes to a random door to leave the room (without checking for traps). there is a
fear trap on the door so he runs away from it and gets all frightened. in retaliation to the "scary" door, he loads his necklace of fireballs (THE WHOLE DAMN THING) into his fireball sling shot and shoots it at the door, rolling a natural 20. we determined he was doing 60d6 to the whole damn room (granted, klepto was immune to fire but i had him roll a saving throw to remain concious).
to say the least, the chicken was dead.

2) on a different year there was a game room that had a magical wheel that gave out prizes depending on what symbol came up. there was a 1/100 chance that you would get this Spock-like elf creature that spouted logic all the time.
well, of course two people rolled that same damn number so the two spocks were arguing over how illlogical it was that there were two of them. then the pcs stuck one of the spocks in a chocolate-covering device and decided to stick him in the infinite loop in the previous hallway (basically it looks like you're falling to your doom, but then you reappear at the top of the chamber & fall again).
the remaining spock had fun arguing the logistics of that.
