When someone of Alan Rickman's caliber acts silly and mugs for the camera it's awesome and nuanced.
When Tim & Eric try to do it, it's like the office cut-ups who think they're so entertaining making ugly fools of themselves.
Simillion Tim and eric have nothing to do with this. They don't make you wait 5 minutes for quality. They just give you a constant stream of mediocre that will eventually, always, make you laugh, unless you're a fucking moron like Binro.
