One evening after dinner, a five-year-old boy noticed that his mother had
gone out and he asked his father, "Where did Mommy go?"

In answer to his question, he was told, "Mommy is at a Tupperware party."

This explanation satisfied him for only a moment. Puzzled, he asked, "What's
a Tupperware party, Daddy?"

The man had always given his son honest answers, so he figured a simple
explanation would be the best approach. "Well, son," he said, "at a
Tupperware party, a bunch of ladies sit around and sell plastic bowls to
each other."

He nodded, indicating that he understood this curious pastime.
