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 Hot Day
It was a stifling hot day and a man fainted in the middle of a busy intersection.

Traffic quickly piled up in all directions, so a woman rushed to help him.

When she knelt down to loosen his collar, a man emerged from the crowd, pushed her aside, and said, "It's all right honey, I've had a course in first aid."

The woman stood up and watched as he took the ill man's pulse and prepared to administer artificial respiration.

At this point she tapped him on the shoulder and said, "When you get to the part about calling a doctor, I'm already here."
