Sorry, Carly Rae but you just can't compete with Hitler, at least not when it comes to "Gangnam Style" mash-ups. "Oppa Führer style," a mashup of Psy’s massive viral sensation with the classic internet meme, "Hitler Reacts," hit the internet this week. The result is, of course, amazing.

Watch above, although we should warn you the video is NSFRH-ish (Not Safe for Rosh Hashanah). 

And if you want to watch Psy himself judge a few of the more popular "Gangnam Style" covers (although, unfortunately, not this one), check out our exclusive interview with the K-pop megastar.
