"Hitler's Reaction" is a scene taken from an old movie where he receives the bad news that an ally he confided in wasn't able to create a coalition force to fight off the invaders. What youtube users do is that they take something big in the media and change the subtitles, for comedy, of course. There is many videos like this. Unfortunately, since this scene is open to the public, some users post a lot of bad language and vulgar content. Fortunately, this is rare, but viewer discretion is advised. Anyway, I hope you find this as funny as I did.
