A old snake goes to see his doctor. “Doc, I need something for my eyes. Can’t see well these days.” The doc fixes him up with a pair of glasses and tells him to return in two weeks.
The snake comes back two weeks later and tells the doctor he’s very depressed.
Doc says, “What’s the problem — didn’t the glasses help you?”
“The glasses are fine, Doc. I just discovered I’ve been living with a water hose the past two years!”
