Waiting for our aerobics class to begin, several of us were standing around in our leotards chatting about fitness and diets. One woman said that her brother-in-law had quit smoking, gone on a diet and lost weight all at the same time.

After a slight pause, she smiled and said, “Well, my sister is pregnant now.”
