John Madden. Nice guy, he did some sort of business in a building my father worked in, saw him in the elevator here and there a few times. I was little and didn't get why it was a big deal.
Madelene Albright. It was boring.
Spike Lee, saw him on the street and the old "40 Acres and a Mule" store he owned. Shorter in person.
Tony "Felix from the Odd Couple" Randall at a doctors appointment. Nice guy, made small talk with everyone.
Saw Robert Deniro at the custom knife counter in Paragon, an expensive sporting goods store. Did a double take, then got over it. He was doing the shy Deniro thing with people.
Lots of rappers - ODB, KRS One, Flavor Flav, Big Pun, Fat Joe, some others. Still talk movies with RA, The Rugged Man here and there.
