Why I hate coconuts
We were playing Dungeons and Dragons and coming up to the big finale boss fight. House rules are that three 20s = instant kill.
The party decided to allow their pet sentient cactus to fight along with them after teaching it how to throw and retrieve a coconut. I went along with it for the laughs, treating it as an improvised weapon with pretty large negatives on dice rolls.
The very first round of the fight went to the cactus. The cleric instructed Needles the Cactus to throw his coconut at the boss.

MFW my uberboss was one-shotted with a coconut
MFW I had to think of how a coconut, thrown by a two-foot tall walking cactus, had managed to slay a black dragon.
