Woman asks:   If I sleep with 3 men, everyone calls me a slut. But when a man sleeps with 10 girls, everyone calls him a real man. How come?     Man replies:   It's very simple. Confucious says 'When one lock can be opened by 3 different keys, it's a bad lock. But when one key can open 10 different locks, we call it a master key'.     P/s: So are you now confused or it this really Confucius ?
