What was it, who did you use it on, did it work, etc. I'm in the mood to laugh.

The other day some guy at the bookstore who was obviously older than me asked me if I lived "around here."
I was like, really? really? seriously? I said no, which was a LIE.
I wanted to ask him "Dude, how old do I look to you? I'm freakin 17 and you're what, 30?"
