A man and a woman were waiting at
the hospital donation center.
Man: "What are you doing here today?"
Woman: "Oh, I'm here to donate some blood.
They're going to give me $5 for it."
Man: "Hmm, that's interesting. I'm here to
donate sperm, myself. But they pay me $25."
The woman looked thoughtful for a moment
and they chatted some more before
going their separate ways.
Several months later, the same man and
woman meet again in the donation center.
Man: "Oh, hi there! Here to
donate blood again?"
Woman: [shaking her head with
mouth closed] "Unh unh."
