Other mistake: As Denny asks "did she sleep in your room?" Alan leaves Denny's hotel room, pulling the door behind him. The swinging door catch is in the closed position, sticking out from the door frame which would prevent the door from being able to shut - the shot cuts a fraction before impact and we hear the sound of the door closing anyway.

Continuity mistake: As Denny walks out of his office after shooting the assailant, Sally moves to the doorway, hands by her sides. Shot cuts to further away and her hand is suddenly up by her mouth. (00:32:40)
Denny Crane: Now, Alan, if all else fails and you think you've lost... pretend you've won! Works for our president.
Trivia: Alan mentions networks even censoring their scripted shows - that's a pointed reference to the fact that ABC executives ordered any explicit references of Fox News to be removed from this episode.
