There have been 3 famous people I have bumped into.
The first was the Celtic (Boston Celtic basketball) player on Newbury Street in Boston, Mass, and I literally bumped into hiim. I was looking at something and all of a sudden I smashed into something and I looked forward to what I hit in the middle of the sidewalk. When I faced forward I just say a guys chest. Now understand I am not short, I am 6' 1" and this guys chest was even with my eyes and I had to look waaaaaaay up and there was Robert Parish! A TALL BLACK GUY who I just smashed into! Little to say I appologized a lot!
Next a few years later I was at King Richard's Faire (a renissuance fair in Carver, Mass) and I bumped shoulders with someone, said sorry, he said no problem and we went on our seperate ways. Seconds later people were coming up to me saying, "Don't you know who you just bumped into?" I said no. and they said, "Steve Tyler!" I said, Who? "Steve Tyler, MAN! You know the lead singer of Areosmith!" Again me saying, Who? They just rolled their eyes and walked on. Hey, I wasn't into their music in high school.
Then this past summer I was next to a very shifty looking bloke in a toliet in a Tempe, Arizona hotel bathroom. He was a creepy looking old guy with a white beard, dressed in black and wearing a black cowboy hat! CREEEE-PIIIIEEEEE!!!! He also had a 'British Accent' which I didn't believe was real at all!
