Who have you known (gone to school with; been acquainted with, etc.) in your life that has gone on to be famous....for better or worse.
Thanks to the Internet, I've been able to "google" people I've lost touch with and always wondered about. I've gotten a couple of suprises in my search. Here's two examples:
T Lewis co-creator of Over the Hedge. We were buds in elementary school. (The dog won't answer my letters! ) Real name is Thomas Leslie Lewis III (aka Tommy Lewis to me).
Dr. Michael Shermer creator of Skeptic Magazine. We went to high school together. Turned into an interesting dude.
There's a couple more names that have gone into publishing, but I barely knew them in high school so, I don't think that counts.
Any one else?
