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 has happened.
An Inspector is sent and is taken straight to the first body. "A XHOSA, 60, died of heart failure whilst making love to his mistress. Hence the enormous smile Inspector", says the Coroner.
The Detective is taken to the second dead man.
"A SOTHO, 25, won the lottery, spent it all on Brandy. Died of alcohol poisoning, hence the smile."
"Nothing unusual here", thinks the Detective, and asks to be shown the last body.
"Ah," says the coroner, "this is the most unusual one. A ZULU, 30, struck by lightning."
"Why is he smiling then?" inquires the Detective.
To which the coroner replies: "Thought he was having his picture taken".
