I bought my husband the Wii gaming system and a few games. I think he'll be really happy with it. Then also some little crap, like a couples massage book, boxers, other random crap that I can't remember.
Re: the man room... We don't have one since out apt is so small, but his buddy has a man-garage (called the G-raj) and a man room in the house. When we have a house, he will def have a man room and preferably a garage. Everyone needs their space and why the hell not! If they want to smoke cigarettes or whatever, let it be contained in their area. I think a man room is the greatest invention to keep a happy home! I so wish I had a house, so Matt could have his room!
