So this is actually a few years old, I guess, but I just found it. The cast of Scrubs dubbed over and edited that perennial holiday classic, A Charlie Brown Christmas. At first it just seems pretty straight-forward, but then it gets sassy, raunchy, and downright perversive. I especially like the new, smooth-talking Schroeder, the flashbacks to Christmas parties past and the crowd's one-liners upon seeing Charlie Brown's pathetic tree. ("Time to deck the halls with your incompetence.") It probably helps to actually know the characters on the sitcom, but I don't and I still enjoyed it.
*UPDATE - Speaking of Christmas traditions being tampered with, did you know that in 1994 they made a sequel to the modern-day classic, A Christmas Story? They called it My Summer Story (ugh) with Charles Grodin (eh) as the dad, Mary Steenburgen (love!) as the mom and Kieran Culkin (wasn't he, like, 3 years old in 1994?) as Ralphie. Like A Christmas Story, this one is based on short stories by Jean Shepard. Unlike A Christmas Story, this one has not snowballed from obscure, cultish hit into mainstream popularity.
Wow, Hollywood, yet another reason to hate you.
