I'm a little bit ill
I'm a little bit under the weather
Stop doing something
Call it a day
Go to Sleep
Hit the sack
Good luck!
Break a leg!
Be easy
Be a piece of cake
The last thing to happen before getting angry
The last straw
Agree with someone
See eye to eye
Be very expensive
Cost an arm and a leg
Something not probable to happen
When pigs fly
Say the truth, tell a secret...
Spill the tea / beans
