The character from Arther Miller's "Death of a saleman".  Before Goerge goes to interview for a job, Jerry tells him not to whistle on the elevator like Biff did in the book.  While George is on his way to the interview, he meets a woman on the train, who he proceeds to take to a hotel (skipping his interview), where she robs him of the $8 he has in his pocket.  When Goerge shows up at Munks wearing a towel, Jerry asks "what happened Biff, did you whistle on the elevator?"
