"Uh-oh! Kwyjibo on the loose!"
— Bart, fleeing his father

The Kwyjibo (Kwyjibo simpsoni) is a species of great ape made up by Bartholomew Jojo Simpson while playing Scrabble with his family to try and cheat his way out of the game. It counts for 22 points, plus triple word score, plus using all of his letters.

They are big, dumb, balding North American apes with no chin and a short temper.


They are aggressive in nature, and their most preferred method of attack is strangulation.
