The old snake slithers in to see his
optometrist.

"Doc. I need something for my eyes. I can't see very well these days."

The doctor fixes him up with a pair of glasses and tells him to return in two weeks.

The snake comes back. He tells the eye doctor he's depressed. "What's the problem?" asks the doc. "Didn't the glasses help?"

"The glasses are fine doc, but I've discovered I've been living with a water hose for the past two years!"
