Where's Mommy?

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...

Then he burst out into laughter, and said, "Come on, Dad! What is it
really?"
