A woman had some problems, so she went to her doctor of twenty years.
The doctor gives her a physical, and then pulls three bottles of pills out of the cabinet and hands them to her. “Take the red pill after breakfast with one glass of water,” the doctor says, “take the blue pill after lunch with two glasses of water, and take the yellow pill after dinner with three glasses of water.
After giving these instructions to the woman, she asks, "Can you tell me what's wrong with me Doctor?”
The Doctor says “Yeah. You don’t drink enough water.”
