Smile Time. Thats a great episode from the final season, and it did have some clever moments, the puppet vamping out and threatening to tear them new puppet holes was brilliant
Oh, "Smile Time" was genius. As well as being clever and hilarious, there's actually a hell of a lot of subtext in there about the deals with the devil that Joss had to make to keep Angel on the air for a fifth season. That boy is not happy. "I do not have puppet cancer!"
