A young couple were touring southern Florida and happened to stop at a rattlesnake farm they discovered along the road. After seeing the sights, they engaged in small talk with the man that handled the snakes.
"Gosh!" exclaimed the young woman. "You certainly have a dangerous job. Don't you ever get bitten by the snakes?"
"Yes, on rare occasions," answered the handler.
"Well," she continued, "what do you do when you're bitten by a snake?"
"I always carry a razor-sharp knife in my pocket, and as soon as I am bitten, I make cut across the fang entry and then suck the poison from the wound."
"What, uh...what would happen if you were to accidentally sit on a rattler?" persisted the woman.
"Ma'am," answered the snake handler, "that will be the day I learn who my real friends are."
