A cliché is "a trite or overused expression," according to The Free Dictionary. My very most favorite cliché is "beyond a shadow of a doubt," for reasons that probably only long-time Mormons would understand. So I'll go with my second favorite: "Well, it's better than a sharp stick in the eye."
Why am I fond of this one? Because it's true; just about anything is better than a sharp stick in the eye. Except a plastic sword in the eye, as Christian accidentally found out yesterday, courtesy of Sir Daniel the Intrepid.
Other clichés often heard at the Perkins Corrall:
You don't have to like it; you just have to eat it.
Speak of the devil, and he shall appear.
Bring it on, Grandpa!
Santa, you're scaring me.
You can do hard things.
Dude, talk to the hand.
What the heck?
Did you want to heat/cool the whole neighborhood?
You said 'pie!'
Your shoe/book/ponytail holder didn't just fall into a wormhole; keep looking until you find it.
What, some of those aren't familiar to you? I can't imagine why not. They are all very useful shorthand for whole conversations; by all means adopt some as your own, if you like.
