How Cliché: Say “yeS”
Today’s batch of cliches focus on the “s” range. It’s “yes” to cliches with “s”.
Scarce as hen’s teeth: When something is very rare.
Don’t use this one much. It makes me wonder how it came into use. Some farmer having fun counting his chickens before they hatch?
Scared of his own shadow: Someone who is often afraid.
Scraping the bottom of the barrel: Taking whatever is left behind.
Second banana: Second in command.
I prefer being second banana. Less pay, true, but less responsibility than the top banana.
Shape up or ship out: Do what is right or correct.
Shoot the breeze: Casually talk about things.
Signed, sealed, delivered: The task is complete.
Skeleton in the closet: scandalous events in someone’s past.
Slow and steady wins the race: Going too fast could cause you to fail.
Squeaky wheel gets the grease: speaking up can get something accomplished.
This one is a personal favorite as I tend to get things done that haven’t been done. Some call that being proactive. Others consider it being squeaky.

“Slow and steady wins the race” said my Dad. And that’s probably why I lost the 50-meter dash.
At least he didn’t advise you to “Stop, Look, Listen.”
I still say all of these!
Snug as a bug in a rug. (One of Mom’s favorites.)
Saved by the bell.
Same song and dance.
Great additions! Especially being snug as a bug.
