DH and I both like dramas - CSI, Law & Order(s), Carnivale, West Wing - as well as documentaries. The only comedy that we ever watch is the Simpsons or Adult Swim (which is Cartoon Network at night.) Oh, and The Daily Show. I love The Daily Show. However, when it comes to picking movies, DH prefers comedies and I prefer drama, action, horror, or dark comedy. My theory is this: DH works all day, comes home, and turns on the tv. He needs something to relax him, so comedy is what he chooses. I, on the other hand, stay at home with a baby and a non-verbal toddler. I turn on the tv, and I need some intellectual stimulation, so I choose something more cerebral. But that's just us; I don't mean to generalize here.
Oh, I just remembered...DH loves The Chappelle Show, South Park, Insomniac, etc. He doesn't watch sitcoms, but yeah, I think he does prefer comedy on tv.
