Joke

In the Lamaze childbirth classes I teach, the first hour is a lecture. During the second hour, the couples get on the floor to practice breathing and relaxation techniques.

The lecture one evening was "Sex During Pregnancy." When I finished presenting the material, I asked if there were any questions.

After waiting a moment, I tried to proceed -- only to be interrupted when the class burst out laughing. It took me a few seconds to realize what I'd said:

"Okay, if there are no questions about sex during pregnancy, let's get down on the floor and practice."
