Man, this episode bored me. Couldn't get into it at all, even when the combination of Cleveland, a Santa suit, and alcohol should have led to laughs. It didn't. The only funny stuff seemed to come from Cleveland Jr., which is starting to become a trend.
They seemed to be going through the entire Rogue's Gallery in the commercial except him (and Mr. Freeze). I don't think avoiding the Joker is in the card-- er, is happening in this series. (unless it gets canceled before they get to it)
