Clown is Manny's cousin and works as a living sign for Bolivia's Finest Quality Used Cars and Petting Zoo while dressed in a clown suit. He apparently harnesses the ability to scare "white folks".
Clown was advertising "Best Wheel Deals!!" at the street corner when Ron Witwicky brought his son to Bobby Bolivia's to purchase a car. Clown complained that the heat was causing his makeup to melt, burning his eyes. This prompted Bobby to tell Manny to take care of his cousin by getting him to take off his clown suit and stop scaring off white folks. This led to an argument between the two cousins while Sam and Ron were picking out a car.
- "Clown" is the moniker given to this character in the credits of the movie.
