The little boy said to his father

It is a woman who takes advantage of the absence of her husband to deceive him. Once the act is over she falls asleep and the lover disappears. But as he
walks past the wardrobe, he hears: – Raaaaa! Whore what is black in there!
He opens the door and takes out a little boy who says to him:
If you do not give me 500 € I say everything to my father.
The lover gives in and goes away. A few days later, the lover and the woman begin again … And when the lover goes past in front of the wardrobe he hears:
Raaaaa! Whore what is black in there!
He opens and the kid asks him 1000 €, the lover yields again. The next day at the table the little boy said to his father:
You saw dad I bought a new bike.
The father then declares:
Listen to my son this bike has cost at least 1500 €, I do not know where you got this money but it should not be very beautiful, so go immediately confess …
The boy runs and heads to the church, he enters the confessional and declares:
Raaaaa! Whore what is black in there!
Then a voice on the other side of the wall declares:
Oh no! You’re not going to tax me here!
