My granddaughter cracks me up. "In a couple of while." is one of my granddaughter's favorite expressions. Obviously, it's a mixed metaphor, mixing "in a couple of minutes," with "in a while."
Here's some more:
"Live and let sleep," combining "live and let be," with "let sleeping dogs lie."
"Lying down with dogs makes trouble," comes from "lie down with dogs, and you'll get fleas."
"Don't rock the ship, " really is "don't rock the boat."
The expressions may be mixed up, but not their meanings. You get the idea.
