How about when people "could care less" - when actually, they
couldn't care less.
Oi! That one drives me bonkers. In fact, there is a relatively new song out in which the singer uses the "could care less" phrase.
No matter how many times I hear it, I shout the proper phrase at the radio. Doesn't work.
Then there was the time I scratched an apostrophe on public restroom signs that initially read "Mens" and "Womens."
I couldn't care less if someone didn't like my actions.
