Like pulling teeth? Who made that up? I’m leaving the dentist. My gums are bleeding. My teeth are sensitive. It should be “like a routine cleaning!”
Sleeping like a baby? Really? That is a good thing? To me, that means waking up screaming and hungry at least once a night.
Sweat like a pig? Blind as a bat? I won’t even go there.
What clichéd similes do you think are way off? What would you like to replace them with?
