 A scene in the film involves this magic sexual potion called Tijuana  Tonic and a chicken mascot. It was inspired by a story related to  Bill Plympton about a guy who started work at a stud farm and  accidentally gave the stud horse an overdose of aphrodisiac. He  claimed that the last time he saw the poor stallion he had broken  out of the corral and was humping a Volkswagen.
