A man and a woman were waiting at the hospital donation centre."What are you doing here today?" said the guy to the woman next to him."Oh I'm here to donate some blood.
They are going to give me $5 for it!" she replied."Ahhh, that's interesting. I'm here to donate sperm, myself. But they pay me $25!" The guy said.The woman looked thoughtful for a moment and after chatting for a little while longer they went their separate ways.
A month later, the same man and woman meet again in the donation centre."Oh, hi there!" said the guy, "Are you here to donate blood again?"The woman then started shaking her head and said, "Mmmmm - mmmmm - mmmmm!"
