Where'd you get that shirt? I actually have a bit I do in my stand-up every once in a while about the Macho Man and Kool-Aid Man in an "Oh Yeah"-off.
I got it from Busted Tees - and they just got more in stock (my buddies and I at work bought one each). Recommendation: the shirts tend to fit small, so go a size up from whatever your usual choice is.
I mark for Brock Lesnar, MVP's theme music, and the Rated R Superstar.
