Not as dramatically mangled, but my wife has a habit of saying someone’s going or talking “ten to the dozen”, and gets quite indignant when I point out that would mean the exact opposite of what she intended.
My wife always says, “Half a dozen of one, half a dozen of the other.” Huh?
She’s a smart lady but a real font of malaprops. One time she was talking about Kate Middleton and said she was “a very stealth woman” when she meant to say “svelte”. Another time she said that no matter how angry she was she would never “cut off her nose and spike her face” (good advice no matter how you put it”. Then there was the time our friend’s son came home after he had run off with a girl. She talked about how “the probable son” had returned.
I love her but sometimes conversations can be very unusual.
