Get the csimug. 
CSI: Crime Scene Investigation, a pretty solid prime time drama series that has its ups and downs. In its fourth season right now, the show has spun off two TV shows, CSI: Miami which is in its second season and CSI: New York, coming out this fall, two PC games, and even a board game.
According to CBS, CSI: Crime Scene Investigation is the most watched drama. The statement is also backed by TV ratings.

Get the CSImug. Slang for having sex with woman who has her period because after you are done having sex, you will leave blood droplets on the sheets or floor. Thus leaving evidence behind!
I approached my girlfriend for sex, and when she said she had her period, I said I was ok with some CSI action.
