h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

The Queen (well not officially, they wouldn't let me, they said I was too rude for my own good. So I saw her, stood about 2 feet away looking through the glass in the door.)
Prime Minister John Major (shook his hand, asked for a decrease on servicemens poll-tax on Live TV! Became a god-damned hero & LEGEND on my RAF Unit)
Eddie Izzard (coming out of the ladies toilets in a transvestite club)
Mick Foley & The Sandman (ECW Wrestlers and very nice chaps).

Oh, and my step-cousin is Hollywood Megastar actor Clive Owen (Sin City, King Arthur, Bourne Identity, Closer). But I've never actually met him, or I can't remember it if i have. I might have when I was really little and our aunts and uncles used to visit us loads.

Oh and British Olympic Sprinter Joan Baptiste. She was in our RAF Station Athletics team. I was on the same team!

Yay!

I've run with an Olympian.

I can also add to that list Gladiator Zodiac (Kate Staples, former British Pole Vaulting champion), DJ David "Kid" Jensen, Reg Holdsworth from Corination Street, former 800m runner Peter Elliot, Paul Darrow (Avon from Blakes 7), author Terry Pratchett (numerous times), 80's pop icon Howard Jones (when I was stationed in High Wycombe), presenter David Vine (who I ran into the back of aged 8 when he came to Coventry to present a Superstars spin-off called Super Teams) and ska legend Buster Bloodvessel patted me on the head when I was 9
