Okay, this might sound weird, but this is what I'm thinking of today. I'm assuming most of you know the idiom, "Don't look a gift horse in the mouth." I know it's about looking at the horse's teeth to check it's age and health, but in my heart I have an alternate history where it's about The Trojan Horse, which doesn't really even make much sense, but it's still living there rent free.
So, does anyone else do this, make up alternate histories for words or phrases? If you do, I'd love examples!
