There is a whole series on YouTube of Epic Rap Battles of History, They did one a few months ago where Freddy Kruger battled Wolverine. I enjoy the whole series but this seem to fit here.

EBR comes up with some pretty good stuff at times. I especially like the ones with their actual historic figures... but I guess I'd be a little biased.
