What's good for the goose is good for the gander.
The bigger they are, the harder they fall.
Be careful what you ask for
What goes around comes around.
He puts his pants on one leg at a time.
The proof is in the pudding.
Whenever I get the feeling that I want to exercise, I go and lay down until the feeling passes.
-WC Fields
There's light at the end of the tunnel.
When in Rome, do as the Romans do.
Too many chiefs, not enough Indians.
It takes one to know one.
What goes up must come down.
