I agree with jzpiano here, we leave it in the pot for the next hand. Many players at home games aren't aware of all the rules and will not be happy if someone else get the chip when their hand was just as good. Since most game are just for fun everyone is happy to leave it in the pot most of the time.

Now if your game aren't just for fun and you don't agree with that then it's the responsability of the host to maintain a book of rules and make sure that everyone understand it. I wouldn't like a home game with that kind of competivity though...home games are suppose to be fun beyond winning money.
