Moved out alone? Then absolutely "Hot Firefighter Guys" calendar (as a jape, funny for straights and gays alike). If it is poorly received you can have a backup Sport's Illustrated girl calendar ready to soften the blow of his solitude.
Moved in with a partner? Get a large format poster size calendar with ample room for people trying to figure it out and working with other people's schedules. Include black sharpies with this one.
