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.
About this sound
South Park clip of Chef's dad retelling how the Loch Ness Monster keeps asking for three fifty, used as a classic bait and switch meme punchline.
This is the extended rant from Chef's father in South Park, retelling yet another encounter where a girl scout, a crustacean, and finally the Loch Ness Monster all turn out to be the same creature begging for money. He builds the story like a serious warning, getting more frustrated as he repeats the line about giving the monster three dollars and fifty cents. The humor comes from the deadpan storytelling, the thick accent, and the sudden reveal that the monster is in disguise again. It lands as an instant recognition joke for anyone who knows the episode.
