Little Johnny

A woman takes a lover home during the day while her husband is at work.
Her 9-year old son comes home unexpectedly, sees them, and hides in the bedroom cupboard. Equally unexpectedly, the woman's husband also comes home. Panicking, she puts her lover in the cupboard, not realising that the little boy is in there already.
The little Johnny says, "Dark in here."
The man says, "Yes, it is."
Boy - "I have a football."
Man - "That's nice."
Boy - "Want to buy it?"
Man - "No, thanks."
Boy - "My dad's outside."
Man - "OK, how much?"
Boy - "£250"
A few weeks later, the same situation occurs and the boy and his mother's lover end up in the cupboard again.
Boy - "Dark in here."
Man - "Yes, it is."
Boy - "I have football boots."
The lover, remembering the last time, asks the boy, "How much?"
Boy - "£750" Man - "Sold."
A few days later, the boy's father says to the boy, "Grab your boots and football, let's go outside and have a game of soccer. The boy says, "I can't, I sold my ball and boots."
The father says, "What?! How much did you sell them for?"
Boy - "£1,000."
The father says, "That's terrible to overcharge your friends like that. That is far more than those two things cost. That was a very wrong thing to do, son. I think we ought to pay a visit to the church and ask the Lord to forgive you for your greed."
They go to the church and the father seats the little boy in the confession booth and closes the door.
Little Johnny says, "Dark in here."
The priest says, "Don't start that sh*t again. You're in my cupboard now."
