Let’s see if I can win the “geezer” prize:
In the early ‘60s I worked for a New York ad agency’s Miami branch. The story was that “Big John Chili” was about to expand their sales into Canada, and thought they’d capture a bit more of the Quebec market if the label was also in French. So the cans were subtitled “Gros Jean Chili”. Trouble is, that’s a slang French Canadian expression:
“Big Tit Chili”
There used to be a small local Mexican food chain called Chi-Chi’s. Slang for tits.
