A man comes home early from work while his wife was having an affair up in her room. She hears him come in the house, so she hides her lover in the closet. The guy hears a voice.
"Sure is dark in here." says womans son.
"Yup," says the guy
"Yhis sure is a nice baseball" the kid says
"Uh, sure kid" the guy says
"I'll sell it to you for 50 bucks" the kid says
"You're crazy!" the man replies
"My dad is right outside" the kid says
"Okay, i'll buy it"

A few days later, the same thing happens. The husband comes home. The wife throws Sancho into the closet.
"Sure is dark in here" the kid says
"Yup" says the guy
"This sure is a nice baseball glove i've got here" the kid says
"How much?" the guy asks
"$100" says the kid
"Deal"

That weekend. The father tells his son to grab his glove so they could play catch. The kid tells his dad that he sold the glove and the ball for $150. The father is disappointed with his son for ripping someone off so he takes the kid to the confessional

The kid goes in, closes the door and says "sure is dark in here"
"Don't start that shit again!" says the priest.
