A couple just started their Lamaze class and they were given an activity requiring the husband to wear a bag of sand to give him an idea of what it feels like to be pregnant.
The husband stood up and shrugged saying, "This doesn't feel so bad."
The instructor then dropped a pen and asked the husband to pick it up.
"You want me to pick up the pen as if I were pregnant, the way my wife would do it?" the husband asked.
"Exactly," replied the instructor.
To the delight of the other husbands, he turned to his wife and said, "Honey, pick up that pen for me."
