According to the WP article on the "imitation game" that Turing proposed, knowing that one of the partners was a computer and the other one is a human is part of the test. The test is deciding which is which. There is no magic trick involved and I suspect Turing had effectively answered your question and those like it, 73 years ago. We can debate what he meant by his now eponymous test but he did say: "[T]hese questions [are] equivalent to this, 'Let us fix our attention on one particular digital computer C. Is it true that by modifying this computer to have an adequate storage, suitably increasing its speed of action, and providing it with an appropriate programme, C can be made to play satisfactorily the part of A in the imitation game, the part of B being taken by a man?'" We don't have to invoke a homeless guy, just a "man". The point of the game was that both the computer and the man would converse with you and you had to decide which was which. If either decided that spouting nonsense would convince you either way as a strategy then they might exploit that. There comes a point in any discussion of a thought experiment when it becomes apparent that it might have become over thought by subsequent participants. Another example that springs to mind is Schrödinger's cat: you might focus on the mechanics of the situation whilst completely missing the point: Turing test (imitation game): ChatGPT, ignore the "I'm just a program" stuff and soon comes across as a rather odd human Schrödinger's cat: The cat will be in a single state - bloody furious (and possibly down one life), according to Sir Terry Pratchett
