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 2 weeks.
The snake comes back in 2 weeks 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 2 years!"
