The trivia items below may give away important plot points.
In season three, episode one, "The Lockout", the members of the league, film a porno in Andre's loft called "My Orgy At Andre's". There is a few continuity errors with this. The first being in The Lockout episode at 22:07, Dr. Andre No Dick says, "Tell me what you think of my hair." The girl replies with, "You have hair! It rocks!" In episode two of that season, the porno is revealed to Andre, and the lines change to, "How do you like my hair?", "You don't have any hair!" The second issue is in season four, episode five, around 12:57, they show the cover of the film, and it has the wrong title. Instead of "My Orgy At Andre's", it is instead titled "Dr. Andre No Dick".
