Let him sleep on your couch. Let him eat your baloney sandwiches.
BUT DO NOT GIVE HIM ONE PENNY!!!!
Definitely give him what he needs: a life-lesson that would save him from many situations like this in the future. It might be tough now, and he might resent you for a bit, but eventually he'll come around and realize what you had to do for him to learn.
