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." The father says, "That's terrible to overcharge your friends like that. That is way more than those two things cost. I'm going to take you to church and make you confess."
They go to church and the father alerts the priest, and makes the little boy sit in the confession booth and closes the door. The boy says, "Dark in here." The priest says, "Don't start that shit again"

Don't talk about those; I was forced to do that MacLaurin shit during my last year at high school. 
Why do you think I stopped taking calculus after high school? Only someone masochistic would ever like doing those things.
