As funny as the series is, there's plenty of reason to keep it an adults-only indulgence. Men are often the brunt of the humor; on the whole, they're portrayed as thoughtless, unconcerned, and emotionally unattached. Some of the male characters view their relationships as torturous, comparing themselves to prisoners. Others are just plain clueless, to the utter exasperation of their female counterparts.
Plus there's the frequently racy subject matter, which touches on affairs, masturbation, and orgasm. In one skit, for example, a man talks about how it feels to think about another guy "plowing one up" his wife; in another, a prostitute names her prices for acts like anal sex, a blow job, and watching a guy "work himself off." Toilet humor is also popular -- sometimes quite literally, as in the case of a dinner party guest who fills a pause in conversation with an extensive description of his recent bowel movement (though that's not the term he uses).
