Deader than a doorknob

Smart like tractor!

In like flint
Why is flint in, and what or who is flint?

Maybe it should say in it like flint, as in all the junk in the flint mi water system.

It's Flynn actually. In like Flynn. Mostly people assume Errol Flynn. I've also heard that it goes back further, to some NY political boss named Flynn.

Makes sense, leave it to me to get it wrong.
In and flynn makes a better rhyme.

you can take that to the bank ===>
try selling it at a flea market ===>
how about unloading it at a garage sale ===>

Many years ago, there was a magazine article about Clint Eastwood titled "In Like Clint".

You can take that to the bank, and smoke it.

how about “dumber than a deadbolt?”

The good,bad and ugly.

"That's the way the cookie crumples". Playing billard's today with a old timer and that is what he said after missing a easy shot .

It’s very crumpling, missing a shot like that. He must have been crumpled to the core.

Dead as a door nail

It's the last straw that broke the camels back.

The two most important days in your life are the day you are born and the day you find out why. –Mark Twain

It's like finding a needle in a hay stack!

He sticks out like a sore throat.

With fronds like these, who needs anemones.

That was a line from ditzy Suzanne Sommers in a Three's Commpany episode.
