One of the funniest (and geekiest things) I've seen in a while is the Geek Week video-cast clip What If Jack Reenacted Marvel Superheroes Secret Wars (YouTube video), in which a bunch of guys go out to a field and reenact scenes from Marvel Comics' Secret Wars.

Quite scary. Even scarier, I happen to have the entire mini-series packed away in the basement from when I collected comic books in middle school. Shut up. ;-p

Note: I've removed the embedded player, as it takes too long to load and the static image is kind of ugly...
