A Woman Donates Her Plasma For Some Extra Cash.

There is a man in front of her in the line for the cashier. She notices that his check is for $200 as he leaves. She excitedly gets to the cashier. To her surprise, the cashier hands her a check for $50. "Wait a second," asks the woman, "how come he got $200 and I only got $50?"

"Well ma'am, you donated plasma and he donated sperm," replies the cashier.

"Oh I see" says the woman.

A week goes by and the woman returns to the donation center. The same cashier is working again. "Oh it's you again," says the cashier, "back to donate more plasma?"

The woman shakes her head no and says, "uh uh", carefully keeping her mouth closed.
