A sexy blonde walked into the doctor's waiting room and couldn't find an empty seat anywhere. Finally, she walks over to one gentleman that was sitting down, and said,
"I wonder if I might trouble you for your seat. You see, I'm pregnant."

The gentleman groaned, coming to his feet and offering the lady his seat.
As the young lady sat down, the man looked her over and said,
"You know, if you hadn't told me, I never would have guessed you were pregnant. How far along are you?"
Looking at her watch, she replied, "Oh, about a half an hour!"
