One day, a man went to see his doctor and told him that he hadn’t been feeling well. The doctor examined the man, left the room, and came back with three different bottles of pills.
The doctor said: “Take the green pill with a big glass of water when you wake up. Take the blue pill with a big glass of water after lunch. Then just before going to bed, take the red pill with another large glass of water.”
Startled to be taking so much medicine, the man said nervously: “Well, geez Doc, exactly what is my problem?”
The doctor replied: “You’re not drinking enough water.”
