Either SECNAV Lehman or The Blue Man Group. The chance to see their props alone was worth the work, seriously incredible engineering mated to child-like imaginations. The fact that they survive touring makes it even more mind blowing.

Joe Biden. I shook his hand at a fundraising event back in the 90s.

I'm on "the other side of the table" at cons, so I've been around a lot. Most famous I've ever sat around and shot the shit with would have to be hanging out with Harlan Ellison and Peter Straub one afternoon. Before I got to the position where I could do that, and not counting anyone I met through my mother, I was Mark Leonard's temporary PA for a day. And I hung out with James Irwin for an hour or so.

I met the govenor of my state once, even shook his hand. Never liked the dude though, plus this state is known for corruption. That's sadly the best I got .
