A famous professor of surgery died and went to heaven. At the pearly gate he was asked by the gatekeeper: Have you ever committed a sin you truly regret? Yes, the professor answered. When I was a young candidate at the hospital of Saint Lucas, we played soccer against at team from the Community Hospital, and I scored a goal, which was off-side. But the referee did not se it so, and the goal won us the match. I regret that now. Well, said the gatekeeper. That is a very minor sin. You may enter.
