A housewife takes a lover during the day, while her husband is at work. Unbeknownst to her, her 9-year-old son was hiding in the closet. Her husband came home unexpectedly, so she hid her lover in the closet. The boy now has company.

Boy: "Dark in here."
Man: "Yes it is."
Boy: "I have a baseball."
Man: "That's nice."
Boy: "Want to buy it?"
Man: "No, thanks."
Boy: "My dad's outside."
Man: "OK, how much?"
Boy: "$250."

In the next few weeks, it happens again that the boy and the mom's lover are in the closet together.

Boy: "Dark in here."
Man: "Yes, it is."
Boy: "I have a baseball glove."
Man: "How much?"
Boy: "$750."
Man: "Fine."

A few days later, the father says to the boy, "Grab your glove. Let's go outside and toss the baseball."

The boy says, "I can't. I sold them."

The father asks, "How much did you sell them for?"

The son says, "$1,000."
