...alchemy, however, is a chaste prostitute...

One of the many entertaining passages on mistupid.com.

A mother took her daughter to the doctor and asked him to give her an examination to determine the cause of her daughters swollen abdomen. It only took the doctor about 2 seconds to say "Your daughter is pregnant."

The mother turned red with fury and she argued with the doctor that her daughter was a good girl and would not compromise her reputation by having sex with a boy. The doctor faced the window and silently watched the horizon.

The mother became enraged and screamed, "Quit looking out the window! Aren't you paying attention to me?"

"Yes, of course I am paying attention ma'am. It's just that the last time this happened, a star appeared in the East, and three wise men came. I was hoping that they would show up again."
