Three smiling corpses are lying in a morgue in Alabama, and a detective goes into the coroner's to find the causes of death. The coroner points to the first dead man.

"This here is Cletus," he says. "He died of shock after winning $20 million on the lottery."

He then moves on to the second smiling corpse. "This here is Bo," the coroner says with a grin. "He died having himself a 'good time' with Trudy-May."

Finally he moves on to the last smiling corpse. "This here is Roscoe," says the coroner. "He died after being struck by lightning."

"Well," asks the detective, "Why in heck was the fool smiling?"

"Oh," says the coroner. "He thought he was having his picture taken."
