Three dead bodies turn up at the mortuary, all with very big smiles on their faces. The coroner calls the police to tell them what has happened.
"First body: Frenchman 60, died of heart failure while making love to his mistress. Hence the enormous smile, Inspector," says the Coroner.
"Second body: Scotsman 25, won a thousand pounds on the lottery, spent it all on whiskey. Died of alcohol poisoning, hence the smile."
The Inspector asked, "What about the third body?"
"Ah," says the coroner, "This is the most unusual one: Paddy from Ireland 30, struck by lightning."
"Why is he smiling then?" inquires the Inspector.
"He thought he was having his picture taken!"
