"Hitler Meme" Downfall?

Karen de Coster reports terrible news: Constantin Films, which owns the rights to the bunker movie Downfall, is trying to get YouTube to pull all "Hitler meme" videos that use footage from the film. 

Anyone who doesn't know what the "Hitler meme" is, please leave the room now.

My two favorites are Hillary and the Housing Bubble. Clearly such videos must be protected under the parody clause, right!?!
