LAUGH LINES

What a Snooze: “Researchers at Stanford and UCLA believe that they have found the cause of narcolepsy. You know--the disease that makes you fall asleep just like that. . . . They say it’s caused by . . . the CBS show ‘Big Brother.’ ” (Jay Leno)

Win Some, Lose Some: “The big [Emmy] winner this year was the White House drama ‘The West Wing,’ which beat out ‘The Sopranos’ in an upset. . . . This just in: The cast of ‘The West Wing’ was found hacked up in the back of a Cadillac.” (Craig Kilborn)

Something in the Air: “The city of Houston has now beat Los Angeles as the smoggiest city in the country. To give you an idea of how bad it is, they’re now executing Death Row inmates by making them breathe the air.” (Andrew Wisot)

Get It?: “Al Gore turned down [George W.] Bush’s offer to debate on CNN’s “Larry King Live” because Gore claims that a lot of people don’t get CNN. Bush said today, ‘Hey, I don’t get CNN either, but my staff explains it to me.’ ” (Leno)

On the Books: “Al Gore was on “The Oprah Winfrey Show.” George W. Bush would have been on Oprah first, but he was afraid she’d make him read one of those books.” (Kilborn)
