I would only tell a dead baby joke around someone I didn't think would be offended. I never tell racist jokes. I do, however, tell and like sexist jokes, both anti-male and anti-female. Only the ones with art, though.
Example of a sexist joke with art: Adam says to God, "I'm lonely. I want someone to share Eden with." God replied, "OK. I'll make you somone. She'll be beautisul, she'll cook for you, she'll clean for you, she'll have sex whenever you want her to and never say a cross word to you." "Sounds great," says Adam. "What'll she cost me?" "Well, she'll cost you an arm and a leg." "What can I get for a rib?"
Example of a sexist joke with no art: Q. Why can't women ski? A. There's no snow between the kitchen and the laundry room!
The latter joke just isn't funny. Not because it's offensive (it's too dumb to offend me) but because it isn't clever. My boyfriend bought Maddox's book of manliness and I couldn't stop laughing, looking at it. THAT shit has art. It's horrible, horrible, horrible, but there's humor in the offensiveness.
