Are these the perils of bull fighting?

While holidaying in southern Spain a man visits a local restaurant – where he sees a diner happily wolfing down two large pink objects. ‘I’ll have those, please,’ he tells the waiter. ‘I’m sorry, Senor,’ comes the reply, ‘but they are cojones – the testicles of the bull killed in the local bullfight. We won't have any more until after the next fight.’ Disappointed, the man returns after the next fight. The waiter remembers him and brings out a plate of two steaming . ‘Just a minute,’ says the man. ‘These are tiny. The ones the man had were four times as big.’ The waiter shrugs. ‘Senor – sometimes the bull, he win.’
