$20 hammock. Guys love hammocks. I would set up the back yard for him. put up the hammock, an ice chest full of beer, string some white christmas lights, cook hotdogs and burgers on the grill, see if you can get a tv set up on the patio for playoff basketball, and invite a couple of his buddies over.
