All the Beer You Can Drink for $1

A guy is walking around town when he sees a bar with a sign advertising "All the Beer You Can Drink for $1!"

He thinks that's a great deal so he goes in, sits down, hands the bartender a dollar, and asks for a beer.

"Sure, right away" says the bartender as he pulls out a tiny shot glass and fills it up halfway.

The man is stunned. "What the hell is this?" he asks.

"That's all the beer you can drink for $1."

Donald R. Griffin

Died 7 Nov 2003 at age 88 (born 3 Aug 1915). Donald Redfield Griffin was an American biophysicist, known for his research in animal navigation, animal behaviour, and sensory biophysics. With Robert Galambos, he studied bat echolocation (1938), a term he coined (1944) for how the bat's ears replace eyes in flight guidance. Using specialized high-frequency sound equipment by G.W. Pierce, they found that bats in flight produced ultrasonic sounds used to avoid obstacles. In WW II, he used physiological principles to design such military equipment as cold-weather clothing and headphones. Griffin also worked extensively on bird navigation. In the late 1940s, he flew in a Piper Cub to observe the flight paths of gannets and gulls. In his career, he pioneered rigorous techniques to study animals in their natural environment.«
