Are you saying that "That's us" is incorrect?
I've always assumed it is "That is us" which seems entirely correct as you are referring to a single group of people (the 'us')....
...or are you also saying that the latter *could* be used but sounds bizarre.
Genuine question.
It's actually not easy once you start thinking about it because daily useage has such a strong effect.
Consider this: "That's me", is what most people would say, simply because it involves the verb to be. Grammatically speaking it should be "That is I". Similarly "It is he" as opposed to "It is him".
Now that I've written this, I've started getting confused myself because the "is" clearly relates to the "that".
I've just thought of another example. You will occasionally here "Those are they" whereas most people would say "that's them" and few of us would find that to be wrong.
A lot of what is held to be correct in English is based on rules which were simply invented in the seventeenth and eighteenth centuries by grammarians who took latin as a model because being classical it couldn't be wrong could it. So whereas you definitely can't split an infinitive in latin, there's no earthly reason why you can't in English. I think the worst culprit for all this nonsense was a bloke called Sheridan who offered courses in "correct" English. Correctness being of course, defined by him.
