I have Yellow and Mario Delux, but they're all packed away at the moment.
And, going outside? Pah! I used to bring my original GameBoy to school! I'd play my GBA SP for a while, then put it away and whip out my brick. Hell, I'd walk around playing Pokemon Red on that! Even the wiggers and emos thought I was awesome for it, too! Having the nads to play Pokemon like that isn't being a dork. Wearing a blue Mario Shirt that says "POWER UP!" while doing that is.
(I'm gonna do that later tonight)
