That gives a deep insight

That’s why I go to the fitness centre regularly now

That takes the biscuit.

That’s the fun of it

That’s going too far

That’s my business!

That village is rather off the map. I shouldn’t like to live there

That sounds good!

That’s beyond me

That’s nasty!

That settles the matter once and for all

That shirt looks good on you.

That gets my goat

That gave the finishing stroke to me.

That is quite something!

That’s a legitimate question

That's real progress.

That is plausble.

That finished me off.

That tops it all!

That’s understood

That is pellucid.

That’s quite enough

That sounds like a good idea to me!

That's pure luck.
