Three dead bodies turn up at a mortuary all with very big smiles on their faces and the police call on the coroner to investigate.
"First body," says the coroner, "Pierre Dubois, Frenchman, 70, died of heart failure while making love to his 20-year old mistress. Hence the Smile,' says the Coroner.
"Second body is Gregory Campbell, Scotsman, 25, won £50,000 on the Lottery. Spent it all on whisky. Died of alcohol poisoning, hence the Smile." he says.
The Police Inspector asked, '"So what about this third body?'" "Ah," says the coroner, "this is the most unusual one. Paddy Murphy, Irish, 30, struck by lightning."
"Why the broad grin, then?" inquires the Inspector. "He thought he was having his picture taken".
