Alsi - you should have lied and told them you were the porn star. As they say on Fark.com - "Potter mistaken for Porn Star. Hilarity ensues"
Speaking of faked identities, I had a friend that was good at doing that. We were at this bar in Boston several years ago, and this girl comes up to him and says "Are you John?" (his name is Ian). The conversation went something like this from there:
Ian: "Yea! How did you know?"
Girl: "Amy said that you'd be wearing the cell phone on your belt"
Ian: "Oh yea, I always keep that here."
Girl: "Well, let me introduce you to my parents."
Ian: "Great!"
Girl: "Here is my Mom, and my dad"
Ian: (talking to mom) "You're far more attractive than they said you were. I see where your daughter gets her good looks from." Mom - blushes
This banter continues on for a bit until Ian excuses himself, and finds me. "We need to leave." "Why?" "Trust me on this one."
Crazy bastard.
