what would you do?

Send the man the pot. If I was called to rule on this I would award the pot to the other player. I am in the process of moving into my new house so I won't give a long explanation here, but in general if you call your hand and can't produce at least that hand you lose if the otehr player mucks. That rule doesn't apply directly here but since it is obvious he misunderstood what you said and there was no hand you could beat he gets the pot.
