That's a cucumber.

That’s all very true, but ...

That’s the way he likes/wants it

That’s about the size of it

That's not my son.

He that will steal a pin, will steal a better thing

That's pure sarcasm.

That is a matter of habit

That’s a wine for you!

That’s all history now

That attracted my attention.

That roused my jealousy.

That’s fantastic!

That's life!

That is enough.

That’s a contradiction in terms: The Federal Government delivers arms in order to maintain world peace

That’s all pie in the sky

That’s not to our taste

That’s just not done

That’s another story
