A man is out shopping when he discovers a new brand of Olympic condoms.  He buys a pack and shows his wife.  ‘They’re in three colours,’ he tells her, ‘Gold, silver and bronze.’  ‘So what colour are you going to wear tonight?’ she asks. ‘Gold of course,’ replies the man.  ‘Why don’t you wear silver?’ replies his wife.  ‘It would be nice if you came second for a change!’
