I've worked with a couple folks with unfortunate names.
One was named Eli Dumas (Do-Maas). He professed that he had a PhD, when in fact he did not. We called him "Dr. Dumb-ass"
At another employer, a vietnamese coworker was name "The Ho." His first name was pronounced "Tay," but that didn't save him from some juvenile snickering.
In highschool, my calc teacher was named Jim Butt. He was an ex air force pilot. His callsign? You guessed it. "Kizma."
