A man and his dog walk into a bar. The man proclaims, "I'll bet you a round of drinks that my dog can talk."
Bartender: "Yeah! Sure ... go ahead."
Man: "What covers a house?"
Dog: "Roof!"
Man: "How does sandpaper feel?"
Dog: "Rough!"
Man: "Who was the greatest baseball player of all time?"
Dog: "Ruth!"
Man: "Pay up. I told you he could talk."
The bartender, annoyed at this point, throws both of them out the door.
Sitting on the sidewalk, the dog looks at the guy and says, "or is the greatest player Mantle?"

Curt Paul Richter

Died 21 Dec 1988 at age 94 (born 20 Feb 1894).American psychobiologist who discovered the body's biorhythms and identified the part of the brain that controls daily cycles of sleeping, waking and other activities. He first wrote about this biological clock in a 1927 paper in which he described how internal cycles control an animal's drinking, eating, running, and sexual behaviour. He also studied the great extent to which animal biological processes can be modifed by learned behaviour. Richter connected the discovery of fire by ancient peoples to significant modifications in habits, communication, learning and even resulted in changes in brain structure. He related behaviour and the biochemistry of sleep, stress, and the onset of disease. Altogether Richter wrote over 250 research papers.«
