For Men Only - S8-E9
Factual error: When Olivia (or whoever) is teaching Russell how to play the Nintendo game she tells him the controls and includes "C and D". The old Nintendo system had no C or D.
Factual error: When Clair and Denise are watching the Bears vs. the Giants game, they comment on how cute player number 16 is. In 1985, nobody wore 16 for either the Bears or the Giants. Former Bears' placekicker Bob Thomas wore it from 1975 to 1984 until he retired. 16 wasn't worn again by the Bears until Tim Lashar, another kicker, wore it in 1987. Also, 16 had long since been retired by the Giants. It was last worn by Frank Gifford.
Chosen answer: That is the song "Open the Door Richard."
