have and have got

No special meaning.

You do = You have the sweetest man in town.

Thank you.
The question still remains, though.
Is it not completely ungrammatical to give the answer 'you do' to the question 'who's got?' ?
Is it a kind of parody of kids' way of speaking? Is there any native speaker who will find the answer above natural?
After 25 years of meticulous study of English grammar I am at a loss.

Is it not completely ungrammatical to give the answer 'you do' to the question 'who's got?' ?- It is fine. There is no necessity for two real speakers to answer with the same verb.
Is it a kind of parody of kids' way of speaking?- No, not at all.
Is there any native speaker who will find the answer above natural? -- I for one do.

Who's got the swee

Thanks a lot!
Does it (like in your answer) carry, any emphasis whatsoever, like in the answer below?
You never buy anything.
Oh, yes, I do buy things here.

Would it sound natural to you if anyone gave the answer below to the original question?
Who's got the sweetest man in town?
You have.

Thank you. Really.

Does it (like in your answer) carry, any emphasis whatsoever?-- That is an interesting question, and the answer is 'No'. I thought about that when I supplied the 'omission' in my response, but rejected it; it is a use of 'do' peculiar to 'have' (and by extension 'have got') only, I think.

Would it sound natural to you if anyone gave the answer below to the original question?

Thanks a lot.
