You have ants in your pants.
You're wiggling.
I hit the nail on the head.
I got it correct.
I'm on top of the world.
I'm doing really well!
Hang in there.
Don't give up!
I'm under the weather.
I'm sick.
I'm feeling blue.
I'm sad.
Walk a mile in my shoes.
Put yourself in my place.
I have a green thumb.
I'm good at growing things.
I'm green with envy.
I'm jealous.
Hold your tongue.
Don't talk.
My eyes are bigger than my stomach.
I took more food than I can eat.
I have butterflies in my stomach.
I'm nervous.
Break a leg.
Good luck!
Time flies.
Time goes quickly.
You're pulling my leg.
You're joking.
Please give me a hand.
Please help.
Don't give me the cold shoulder.
Don't ignore me.
Don't cut corners.
Do your best instead of skipping something.
Don't spill the beans.
Don't tell the secret.
You crack me up.
You make me laugh.
I'm in a pickle.
I'm in a difficult situation.
That's a piece of cake.
That's easy.
My words went in one ear and out the other.
You didn't listen to me.
It's raining cats and dogs.
It's raining hard.
When pigs fly.
Something that will never happen.
