My Woz story:
During college I was in an airport heading somewhere for a competition with a friend. I spotted someone familiar out of the corner of my eye, and turned to see Woz about to get on an elevator to go up to one of those Delta members lounges or whatever.
He was maybe 100ft away, so I yelled out, "Hey, Steve!" He turned around, and I said, "Wish me luck!" and gave him a thumbs up. He returned the thumbs up, yelled "Good luck," and got in his elevator.
I won the competition.
