"Lover and son in closet" joke

A married woman is having an affair. Whenever her lover comes over, she puts her nine year old son in the closet. One day the woman hears a car in the driveway and puts her lover in the closet, as well.
Inside the closet, the little boy says, "It sure is dark in here, isn't it?
"Yes it is," the man replies.
"You wanna buy a baseball?" the little boy asks.
"No thanks," the man replies.
"I think you do want to buy a baseball," the little boy says firmly.
The man considers the position he is in for a moment. "Uh, I see. You're right, I do want to buy the ball. How much?"
Twenty-five dollars," the little extortionist replies. "TWENTY-FIVE DOLLARS?!" the man repeats incredulously, but then shakes his head and complies to protect his hidden position.
The following week, the lover is visiting the woman again when she hears a car in the driveway and, again, places him in the closet with her little boy.
"It sure is dark in here, isn't it?" the boy starts off.
"Yes it is," replies the man.
"Wanna buy a baseball glove?" the little boy asks.
"OK. How much this time?" the hiding lover responds.
"Fifty dollars," the boy replies and the transaction is completed.
The next weekend, the little boy's father says,
"Hey, son. Go get your ball and glove and we'll play some catch."
"I can't. I sold them," replies the little boy.
"What did you get for them?" asks the father, expecting to hear about lizards and candy and preparing a lecture about how valuable the baseball and glove were.
"Seventy-five dollars," the little boy says.
"SEVENTY-FIVE DOLLARS?! That's thievery! I'm taking you to the church right now.
You must confess your sin and ask for forgiveness!" The father hauls the child away.
At the church, the little boy goes into the confessional, draws the curtain, sits down, and says "It sure is dark in here, isn't it?"
"Don't you start that shit again," says the priest.
