Fractured Cliché: Let sleeping horses lie
Correct Cliché: Let sleeping dogs lie
I have no idea why I would say this particular fractured cliché. I don’t have a horse, nor have I spent much time around them. They usually don’t even lie down when they sleep, they normally stand.
On top of that, I live with two dogs and always, always let them sleep (unless circumstances dictate they be disturbed). And unlike a horse, they always, always lie when they sleep. (You can’t trust a word they say when they’re sleeping.)
I will admit that I’ve only made this mistake once, but there’s another sleep-related cliché mistake I’ve made on several occasions. Here it is:
Fractured Cliché: He’s eating with the fishes
Correct Cliché: He’s sleeping with the fishes
Being from Chicago, you would think I would have gotten this one right.
May the farce be with you!
