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.
I don't think it's gotten better and better. It's still good, and the run with Heather Graham at the beginning of the year was perhaps their toppest notch, but in the last couple seasons it's gotten overly broad, overly goofy, and overly hammy, IMOHO.
