In this night of Open Lines, there was a special emphasis on the subject of invisibility and what callers would do if they could be invisible. Tim from Tempe suggested the United States could use invisibility to hunt down Osama bin Laden and members of the al Qaeda terrorist organization. Art pointed out that terrorists could also use the technology to launch more devastating attacks against us. John from Long Island said if he were invisible, he'd visit the Playboy Mansion.

Frequent caller and self-proclaimed 'God's ten-star general in the war against media pornography,' J.C. phoned in to sound off on a variety of topics. J.C. railed against Halloween, warned about 'lesbian Tupperware parties,' and suggested Hawaii was punished by God with earthquakes because of exotic dancing. During J.C.'s 18-minute rant, Art allowed other callers to speak with him (at their own risk, of course).

In the first hour, Dr. Roy Spencer discussed climate change. Spencer thinks there is sufficient evidence for global warming, but is not convinced that mankind is responsible for it. He said surface thermometer data from the North Pole indicates that it was just as warm there in the 1930s as it is today. He also commented on Jim Hansen, a NASA climate scientist who believes the planet's current warming trend has been caused by human-produced pollutants. Even if man is ultimately responsible for the warming trend, Spencer hypothesized, "there's no way to turn it around in the coming few decades because mankind depends on fossil fuels so much."
