Terry Pratchett was probably the coolest
The only deliberate attempt to meet anyone was a book signing with Terry Pratchett at the Waterstones in Kingston. He was very nice and wrote "Dear Claire, remember the yodelling stick insect!" in my copy of Thief of Time.

The best accidental sighting of a famous person by me was seeing Richard O'Brian in Center Parcs when I was 6 (maybe he actually lived in the swimming pool that looked like the Crystal Dome).

Also, I went to Reading festival with my fella, Ed, a couple of years ago to see Muse. We didn't meet Matt Bellamy (although I did manage to be right at the front when they played Top of the Pops, he was wearing a ladies' top as I recall). However, Ed was watching Wolfmother whilst waiting for me to get back from the loo and a bloke next to him remarked that they were rather good, to which Ed concurred. They carried on watching the band for a bit and the bloke wandered off. Ed then realised he'd been standing next to the drummer from Dirty Pretty Things. Which was nice.

Finally, we went on a college trip to see some prestigious daytime talk show with Gloria Hunniford presenting, which was as boring as it sounds except she had Harry Hill on and he gave me a funny look because I was doing an impression of Wallace from Wallace & Gromit for reasons which escape me.

Oh and my mum made friends with Bradley Walsh on holiday in Dubai and my dad once got mistaken for Pat Jennings at a train station in Preston.
