"It Sure Is Dark In Here" 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.
"Do you wanna buy a baseball?" asks the little boy.
"No, thank you," the man replies.
"I think you do wanna buy a baseball," the little extortionist continues.
After considering the position he's in, the man says, "Fine. How much?"
"Twenty-five dollars," the little boy replies.
"TWENTY-FIVE DOLLARS?!" the man repeats incredulously, but complies to protect his hidden position.
The following week, the lover is visiting the woman again when she hears a car in the driveway. Again, the woman places her lover in the closet with her little boy.
"It sure is dark in here, isn't it?" the little boy starts off.
"Yes it is," the man replies.
"Do you wanna buy a baseball glove?" the little boy asks.
Realizing his disadvantage, the hiding lover replies, "Sure. How much?"
"Fifty dollars," the boy replies and the transaction is completed.
The following 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," the little boy replies.
"How much did you get for them?" asks the father, expecting to hear the profit in terms of trading cards and candy.
"Seventy-five dollars," the little boy says.
"SEVENTY-FIVE DOLLARS?!? That's thievery! I'm taking you to the church right now. You are going to confess your sin and ask for forgiveness," the father says as he 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 in here," the priest says!
