Possibly one of the most famous uses, the rival of Marty McFly in the movies, Back to the Future.
Biff is one of the characters who appears frequently in Oxford Reading Tree books - practically every child in England over the past twenty years has read them in infant and primary school.Biff was a girl, who had brothers called Chip and Kipper. Funny stuff.
On Sesame Street, Biff was a Muppet construction worker. He was very talkative and had a strong New York accent. His sidekick was the always silent Sully.
