During this episode, Earl mentions a dream where he gets hit by a car and is in a coma. Then saying that "nobody wants to see that". This might be a reference to low ratings from the previous season where Earl was in a coma.
Greg Garcia realized well ahead that the show would be canceled after season four, hence the attack at network executives at the end of this episode.
In Randy's threatening letters to Ernie he lists celebrities who agree "fish wings" should be served everyday. Burt Reynolds is on his list. Burt Reynolds was cast in earlier seasons as Richard Chubby, the richest man in Camden and owner of Club Chubby.
Earl's middle name is revealed as "Jehoshaphat".
