Maternity clothes stores

I have the weekend all to myself; the missus is going shopping with her sister at some maternity clothes stores. Her sister is having a baby, not her so I get to do what ever I want this weekend. This is rare opportunity so I have to make the best of it. What should I do? Go to the game with the boys? Poker games with the boys? Get piss drunk with the boys? Sounds good but are they going to be free though? Looks like just me in front of the idiot box all weekend.
