Three dead bodies turn up at the mortuary, all with very big smiles on their faces. The coroner calls the police to show them what's happened. A Detective Inspector is sent and is taken straight to the first body. "Englishman, 60, died of heart failure whilst making love to his mistress. Hence the enormous smile, Inspector" says the Coroner. The DI is taken to the second dead man. "Scotsman, 25, won a thousand pounds on the lottery, spent it all on whisky, died of alcohol poisoning, hence the smile" The DI is taken to that last body. "Ah" says the coroner, "this is the most unusual one. Irishman, 30, struck by lightning" The DI looks puzzled, "Why is he smiling then?" he asked. "He thought he was having his picture taken" replied the coroner.
