Offer to help him search for a place/job/whatever, but even if this guy isn't a terrible person, this could easily be a case of a week or two turning into a month or two and then you have to be the "asshole" kicking this guy out into the streets in a place where he doesn't know anybody.

edit:lol poopyhead isn't quite what i had in mind. nipples are ok it seems, but no "A" words.
