I've never actually met a celebrity. Last summer when we were hiking in Yosemite we hiked past Napoleon Dynamite's twin brother. I didn't notice him, but my BF loves Napoleon Dynamite and punched me in the arm and made me look. I said "Aw, yeah, that's him. Why was that worth punching me?!" It looked like he was helping a group of kids. I guess it could have been Jon Heder himself, but we assumed it was his twin.
