I did some phone polling for a local candidate and one of the names on my list was Butts. I needed to talk to the wife. The husband answered the phone. I said, "Hello, I would like to talk to Mrs. Butts." He says, "This is Mr. Butts, she is not in right now." By that point I almost lost it.
I do academic research and in a German journal from the 1890s I saw a man with the last name F*ck. Yes, that word. And he had a PhD. I hope that that last name was changed forever in that family.
It goes the other way, too. I worked with a lady whose married name was Coontz. One mispronounced it at one’s peril. So imagine the merriment when a newly hired receptionist announced over the company-wide PA that there was a phone call for Mrs. you-know-who.
