Take Me out of the Ball Game - S3-E24
Factual error: Near the end of the episode, Dale Gribble saves Team Strickland by catching a home run ball, hit by Kurt Bevacqua, with his hat. This wins them the game. However, according to the MLB Rulebook, if a player catches a fly ball with their hat, the batter takes three bases, meaning the game would continue and Bevacqua would be at third base. (00:21:00)
Answer: If you are talking about the "Thou shalt not do this, thou shalt not do that" song, I'm not sure if a song like that actually exists. Green Day, the guest voices on the episode, might have just been improvising to keep their appearance from being too obvious.
