A friend of mine has a friend in Colorado, I think, named Dick Head. He introduces himself that way, not Richard Head.
In Santa Fe a guy named Peter Handler had a liquor store with his name in huge letters above it. Always made me snicker.
Then there was always Doctor Seymour Butts, but I am not sure he was as real as the others I mentioned.
A group of us skipped school one day and went to downtown Pittsburgh to go up to the top of the Gulf building. We had to sign in. Everyone used funny names Jim Nasium, Peter Goesinya etc. Hubbard Booze used his real name and was denied admission.
