Did you see the clip in Jackass 3 where Johnny Knoxville took an open field, no pads tackle from Jared Allen!? That was just insane! It wasn't just some playful hit either - you could literally hear Knoxville's rib cage crack when Allen hit him...like, that sickening kinda crack.

I hate to admit it, because I know it makes me a whore, but for the right amount of money I'd let Ray Lewis hit me.
