Pregnant Woman on the Subway

A woman had just left her doctor, where she'd just learned she was pregnant.

On the way home, she was holding onto the strap in the subway and was growing more weary by the moment. She asked the man seated before her, "Sir, I wonder if you would let me have your seat. I'm pregnant."

The gentleman did just that, and then, observing her for a moment, he said, "You seem very glowing and not at all removed from a perfect shape. May I ask how long you've been pregnant?"

"Oh, about thirty minutes," she replied, "and I sure am tired!"
