things to do on a rainy day ...
1) play online poker
2)go to the casino and play poker( ok its still gambling but might as well do something productive like losing your shirt or winning someone's spouse/business on the final table
3) watch old tv shows and wonder why did you ever like them in the first place 9or try to find the sexual innuendos that were implied but you didn't catch them the first time
4)clean the house and find those missing socks or earrings
5) do laundry! If you go out in the rain ,your clothes will get wet anyway and they will have to dry.
6)call people and complain how miserable you are because you have nothing to do because its raining!
