One afternoon, a man goes to his doctor and tells him that he hasn’t been feeling well lately. The doctor examines the man, leaves the room, and comes back with three different bottles of pills.
The doctor says, “Take the red pill with a big glass of water when you wake up. Take the green pill with a big glass of water after you eat lunch. Then just before going to bed, take the blue pill with another big glass of water.”
Startled to be put on so much medicine, the man stammers, “Jeez Doc, exactly what is my problem?”
The doctor replies, “You’re not drinking enough water.”
