(Kind of a funny story)
A friend and I were near Beverly Hills while in LA one summer doing the (sort of) touristy thing. So we are walking down the sidewalk and ahead of us about 10 meters a big Mercedes is parallel parking... then Steve Martin gets out of the passenger side. I guess i was looking stunned with my mouth open because he just looks at me, points at me and says "um.. no".
Maybe he thought i was going to ask for an autograph or something.
