A Big Glass of Water
A man goes to the doctor and tells him that he hasn't been feeling well. The doctor examines him, leaves the room and comes back with three different bottles of pills. The doctor says:

"Take the green pill with a big glass of water when you get 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 big glass of water."

Startled to be put on so much medicine the man stammers:

"Jeez doc, exactly what's my problem?"

Doctor says,

"You're not drinking enough water."

A large difference
A man went to the doctor's. The doctor came in and said,"Well, I've got some good news and some bad news. The bad news is that you have an inoperable brain tumor. The good news is our hospital has just been certified to do brain transplants and there has been an accident right out front and a young couple was killed and you can have whichever brain you'd like. The man's brain costs $100,000.00 and the woman's brain costs "$30,000.00." The patient could not help but ask, "Why such a large difference between the male and the female brain?" The doctor replied, "The female brain is used."
