A friend of mine was working as a nurse in a West Australian coastal town when a tourist came into the medical center with a fishhook lodged deep in his hand. Since it was the weekend, my friend had to summon the doctor from home.
The tourist was dismayed to see that the doctor was young, had long hair and wore sandals and a very casual shirt. "You don’t look much like a doctor to me," he said dubiously.
The doctor examined the hook in the tourist’s hand and responded, "And you don’t look much like a fish to me."
