Dad's in an impatient mood today.

They're on pins and needles.

He has ants in his pants.

He was in a twitter.

He is always in a fidget.

I have some butterflies in my stomach.

I began to stir about 4:30 in the morning, but I didn't get up until 6:00.

What's the matter? You've been fidgety since this morning. You seem out of it.
