Sim Heil

Sim Heil, also known as Der Untersim, was the earliest known Downfall parody on YouTube. The video was first uploaded on August 2006 by DReaperF4 with Spanish subtitles. It became so popular that an English-language version of the subtitled video was made.

In the video, Hitler rants about the release of Microsoft's Flight Simulator X, citing issues within the game as well as the lack of certain features in the demo. Like most of the early Downfall parodies, it was taken down in 2009 by Constantin Films during the 2009-2010 DMCA crisis.
