Play some pickup basketball at the gym, perhaps tennis, hit up the driving range, call every dude you know to go to all the ethnic restaurants your wife does not enjoy. Go watch the star local high school football, basketball or junior college team in town.

Take yourself to a Stand Up Comedy show she may not approve of. Do you have any friends with dirtbikes? Call them, also hit up the expensive fast go carts!

You forgot how to be fun, because you are responsible and married, but come on, live it up while she is gone. Also every meal you do not eat out, that you cook at home should be some sort of nachos or quesadilla.

Have buddies over to watch Snatch, or The Usual Suspects.
