Usually I'm with the spirit of the jibe and quite up for the banter. I like banter.

On rare occasions, I get bored with dullard jokes and I'm quite happy to offer the humourist the opportunity to be battered to a pulp by the "man in the dress".

I've never had to resort to such means yet. If I get close, people usually deduce where the boundary line is before it all goes pear shaped and we agree to differ.
