I used to work for a manager who was in his late sixties and was ready to retire.
He grew up in an industry where there were no women and apologized everytime he said something inappropriate. He was a sweetheart.

Whenever he was referring to someone needing to do something they didn't want to do such as redoing someone else's work he would always say "they are going to need to swallow hard."

I don't believe anyone ever pointed out the oral sex connection.
