One day, two young brothers in Rome, aged 12 and 14, came home carrying a 20- and a 50-euro note. Their mother immediately asked where they had gotten so much money. “Well,” said the younger boy, “we were standing outside a brothel when a man walked out.

We told him we knew where he’d been, so he paid us 20 euros to keep quiet.”
“Then we followed him home,” added the older brother. “When we told him we also knew where he lived, he gave us another 50 euros and begged us not to say anything.”

The mother was horrified. “That’s terrible behavior. You should be ashamed of yourselves. Go to church immediately and confess your sins.”
The boys obediently went to confession and returned later that afternoon.

This time, they were carrying 100 euros.
When their mother demanded an explanation, the boys smiled.
“Now,” they said, “we also know where the man works.”
