[Context: We’re a party of 5, who’ve stumbled into an underground lair full of pretty nasty enemies. We’ve been playing for a while, and have finally managed to find somewhere quiet to pause to take stock of our situation. We’re stood near a door, deciding what to do next. One of our party is a human warrior, who is known for asking to do slightly wacky things in dangerous situations.]
Human Warrior: (tries to peek through a keyhole to see inside a room, and rolls a natural 1.) ‘Whoops!’
DM: ‘You lean on the door, and it swings open! You stumble into the room, stopping only when you hit a table, and you hear the door slam shut behind you, trapping you alone in the room with four bandits! They aren’t pleased to see an intruder, and draw some rather nasty looking weapons’.
Human Warrior, immediately after DM stops talking: 'Can I do a provocative dance on the table to distract them?’
DM, slightly incredulously : 'I mean… I guess? Roll me a 20 and you can do that.’
Human Warrior: (rolls his first 20 of the entire campaign)
DM: (pauses for a good ten seconds, then sighs loudly) You climb on the table, and begin to dance. The bandits, rather out of character (pointed look at the instigator of the whole thing) put away their weapons and watch you dance.’
Human Warrior : 'If I roll another 20, can they all pass out at the brilliance of my dance?’
DM: (stares, then says) 'Sure. Chances of that happening are slim’
Seconds later, the DM is sat with his head in his hand, four unconscious bandits, as our human warrior celebrated his second natural 20 in 2 rolls. Everyone else round the table is in hysterics. Our warrior now introduces himself to NPC’s as a 'Legendary Dancer’. Our DM has outlawed anything dance-related.
