HUH ?
You pick up a gorgeous hitchhiker. That's good.
She faints inside your car. That's not good.
You take her to a hospital where they say she's pregnant and congratulate you. That's bad.
You say you're not the father, but she says you are. That's stressful.
You request a DNA test to prove it's not yours, which it does. That's a relief.
The doctor adds that you're infertile. That's terrible.
Then you remember you have three kids at home!
