[Hm? She sits up again, frowning up at the paper he's holding up. She's not sure why he's handling a blank sheet of paper, but it's the tone he's using with her that's... odd. So--]
Okay, there's a woman giving birth, right? And her husband's with her, they're at the hospital, and she's in a lot of pain, screaming, and the doctor says, [here she puts on an affected deep voice; not a bad one, either] "I have a machine that can split the pain between the mother and the father". The husband says go for it, even though the wife says he won't be able to handle it. The doctor turns on the machine, but the husband is all -- [different deep voice this time] -- "this is great! I dunno why women complain so much."
[The joke continues as the amount of pain divided between husband and wife gets more and more disproportionate -- complete with animated gesturing and different voices for each person -- until the husband agrees to endure all the pain, still not feeling a thing.] So, a day later, they leave the hospital and go home, and the mailman is lying dead on their doorstep.
