As far as I know, I have no met any actors or anything really big like that.

However, I've met a small handful of musicians. I have had the pleasure of hanging out with Evanescence a few times in the past, both the current and long gone members of the band. I've met Korn, and was terrified by one of the guitarists. Of course I've known The Fray for awhile, and never thought they'd make it big. Silly me.

And Michael Bublé, apparantly. I had no idea who he was at the time, though.
