Ah, well. All good things must come to an end. Apparently the raft of Hitler gets upset at (pick a topic) video parodies that uses the film Downfall as its video starting point are being pulled from YouTube. The film's makers Constantine Films has thrown their own little snit and the videos are beginning to be taken down.
This really got noticed and gained some Internet traction today because there was a video made over the recent missing/stolen/Gizmodo buys it new iPhone flap with Hitler throwing his usual tizzy and that video quickly got pulled. At the moment, you can still see it here but I don't know for how long.
