"Whaddya know?"

They seldom ask me this twice, as I begin with
"It takes a hell of a big dog to weigh a ton."

and proceed to

"If two systems are in relative motion with a uniform linear velocity, it is impossible for members of one system to ascertain by observation or measurement of phenomena, anything about the other system, other than that there IS relative motion."



also: "What's up".....answer.."Down....have you priced good sleeping bags lately? Down is WAY up!"
