Some of mine, and some others…
The old chestnut that broke the camel’s back.
She threw the towel with the bathwater.
Don’t look a coincidence in the mouth.
Wouldn’t touch him with bar of soap.
We have to get all our ducks on the same page.
The fan hit the roof.
She was breathing down my throat.
Put that in your hat and smoke it.
Burning the midnight oil at both ends.
To kill two birds with one bad egg.
Got to get my act in gear.
Right up your cup of tea!
