I had a coworker that referred to her ex as Richard Cranium.
:-)
I have a friend who actually met a man in Colorado who introduced himself as Dick Head. My friend is very proper and she almost died of embarrassment.
Then there is that guy in Santa Fe NM named Peter Handler. Mr Handled had a liquor store with his name in 2 foot tall letters on it. I thought it was a joke name but then I saw his picture in the paper. He was real ya’ll! :)
Exes always do keep it classy...
