Some women hired a male stripper for a bachelorette party.
He goes through all the gyrations, titillations, which are expected of a male stripper, taking a little off at a time until finally he is dancing around in his g-string/thong or whatever it is called.

He dances in this state of undress for a period of time, with the women coaxing him to remove even the thong, which he does and drops it to the floor.

One of the women picks it up and sort of shakes it and asks while looking at the stripper.

"Where's the rest?"
