Gary and Martin were standing...

Gary and Martin were standing at the urinals in a public lavatory, when Gary glanced over and noticed that Martin's penis was twisted like a corkscrew.
"Wow," Gary said. "I've never seen one like that before."
"Like what?" Martin said.
"All twisted like a pig's tail," Gary said.
"Well, what's yours like?" Martin said.
"Straight, like normal," Gary said.
"I thought mine was normal until I saw yours," Martin said.
Gary finished what he was doing and started to give his old boy a shakedown prior to putting it back in his pants.
"What did you do that for?" Martin said.
"Shaking off the excess drops," Gary said. "Like normal."
"Shoot!" Martin said. "And all these years I've been wringing it."

National light-pollution law

In 2002, the first national law prohibiting "light pollution" went into effect. The Czech Republic became the first nation to outlaw excess outdoor light. All outdoor light fixtures in the country must be shielded to ensure light goes only in the direction intended, and not above the horizontal. Czech astronomers had lobbied for the legislation. Light from street and road signs bounces off molecules in the atmosphere, making skies less dark. This light pollution is a particular problem for astronomers since even low levels of man-made light from distant cities can obscure their view of faint objects far away in space. Better designed, non-polluting light fixtures should give everyone better more energy efficiency and reduce glare on roads and in residential areas.[Image: Skyglow 120km north of Adelaide, Australia.]
