It's like water off a ducks back

Lie on your back and think of England 

We will have to put that on the back burner for now

Back to the future!

You are back in the saddle

Never look back

Back in my younger years.....

Looks like it's back to the drawing board

If looks could kill

Never look back

Never say never

I've never heard of such a thing

I never do that.

Knowing is not enough; we must apply. Thinking is not enough; we must do.

Enough is enough 

Enough determination to quit smoking!

I can't thank you enough

Whether you think you can, or you think you can't – you're right!!!

Who do you think you're talking to

Who's she, the cats mother? 

Cat's in the cradle. 

Don't be such a scaredy cat 

The cat's pajamas

you're the cat's meow

I'm going for a cat nap
