Federer once cleaned toilets as punishment for smashing racquet
Twenty-time Grand Slam champion Roger Federer, who turns 37 today, was asked to clean toilets as a punishment, after he smashed his racquet as a teenager. Federer was 16, training at Switzerland's national tennis centre in Biel when he threw his racquet at a courtside curtain, ripping it. Federer's then coach Peter Lundgren described him as a "ball of stress".
