Laughed her head off
To laugh a lot
Speak of the devil
The person we were just talking about showed up
Under the weather
Feeling sick
You can say that again
That's true, I agree
Call it a day
Stop doing something or stop working on something
Cutting corners
Doing something poorly in order to save time or money
On the ball
Doing a good job
A laugh a minute
Very funny
Pay through the nose
Pay more than a fair price
Lend a hand
Help someone
Put your foot down
To stop something from happening
A blessing in disguise
A good thing that seemed bad at first
In the twinkle of an eye
Happens very quickly
By word of mouth
People tell it to each other rather than it being printed in written form
Miss the boat
It's too late
Pull someone's leg
Joke with someone
Break a leg
Wish someone good luck
It's not rocket science
It's not difficult
Pull yourself together
Calm down
It tickled my ribs
Made me laugh
