I had a great-uncle named Captain.
It wasn’t a problem until he got drafted in the army. When they decided they couldn’t call a private Captain, they decided they wanted to use his middle name, which happened to be General.
They called him Captain.
Guy got a new driver, he asked him what his name was.
"Charles, sir."
"I call my employees by their last name. What is your last name?"
"Darling, sir."
"Well... drive on Charles!"
