Call it a day
stop working
Use your noodle
use your brain
Sounds fishy
does not sound right
Monkey business
silly or foolish things happening
Straight face
Not laughing or smiling
Bite your tongue
don't say something; usually something bad
Took the words our of my mouth
say what someone else is thinking before he can say it himself
Behind someone's back
do or say something when someone doesn't know it; usually something bad.
Drag your feet
do something very slowly
In a pickle
in trouble
Money doesn't grow on trees
its too expensive to buy everything they want.
Hold your horses
wait
Bring home the bacon
Earn money
Pay an arm and a leg
Pay a lot of money
Throw in the towel
Give up
On the tip of my tongue
Can't think of the word you want to say
