He was at home one day and he heard some moaning and groaning coming
from his mother's bedroom. He hastily peeked through the keyhole and saw his
mother lying on the bed, naked, rubbing herself and saying "I need a man,
God, I need a man!"
The boy saw this ritual several times, until one day he peeked through
the keyhole and saw a man on top of her. He immediately ran to his room,
took off all his clothes, and rubbed himself while saying: "I need a bike,
I need a bike!"
