 When talking about starting a band, Earl references another band  that was started by two brothers, "Van Halen". The two list items  Earl deals with in this episode are #50 (Kicked Lead Singer out of  Band) and #51 (Slept with Ralphs Mom) or "5150", the name of the  first Van Halen album with Sammy Hagar (after David Lee Roth was  kicked out of the band).
