The son of a Saudi mogul goes to study in Europe. One night, the phone rings at the house of his parents. Dad: 'How's your life going, son?' Son: 'It's going well, dad.' Dad: 'Is something wrong? You don't sound happy.' Son: 'No Dad, everything's fine. Berlin is wonderful, the people are nice and I really like it here.' Dad: 'Son, tell me the truth. I know something's not right.' Son: 'Well dad, to be honest, I am a bit ashamed to drive to my college with my pure-gold Ferrari 599GTB when all my teachers and many fellow students travel by train.' Dad: 'My dear son, why didn't you say so earlier? I will send you more funds this instant. Please stop embarrassing us and go and get yourself a train too.'
