An elderly snake went to the doctor and told him:
“Doc, my eyesight is so bad, I can’t see to hunt any more. I think I need a pair of glasses.”
So the doctor fixed the snake up with a pair of glasses and told him to come back if he still couldn’t manage.
Two weeks later, the snake was back in the doctor’s office.
“I’m depressed,” he complained.
“Why, what’s the problem?” asked the doctor.
“Haven’t the glasses helped?”
“The glasses are fine,” sighed the snake.
“But I’ve discovered that I’ve been living with a garden hose for the past three years.”
