The clip comes from the South Park episode The Succubus, first aired in 1999, where Chef's parents visit and his father keeps derailing conversations with tales of the Loch Ness Monster. Each story ends with the monster asking for three fifty, a deliberately tiny amount that makes the epic encounter funnier. The bit became one of the show's most quoted running gags, spawning tree fiddy as slang online for a scam request or an anticlimactic ask, and the audio still circulates as a reaction to any suspicious storyteller.
