"A small boy is wandering" joke

A small boy is wandering in a hotel, and hearing some noises
decides to open a door. He says "Wow, it's dark here!"
You can imagine that there's a man with a woman in that room...
The man asks, "What do you want? Here's a buck, leave us alone."
A bit latter, the boy goes back again, opens the door, and says:
"Wow, it's dark here!" "Not you again! Here, take this and
go buy yourself something." And the boy goes out with 2 bucks.
The following morning, the boy feels some remorse, and tells what happened
to his mother. She says: "That's wrong. You should go to the church,
and confess yourself."
So there he goes. Entering the booth, he says: "Wow, it's dark here!".
To which the priest says: "Are you following me around?"
