Lorelai: How does Charlie Rose screw up your REM sleep?
Luke: Because he's always got some guy on pushing a book about how everything's all going to hell, or they're going to pass a law, how everyone with a nose ring is going to get shipped off to China. Suddenly you're depressed, thinking we're all going to die and don't drink the water, there's anthrax in my bagel - and bam, there goes your REM sleep.
Lorelai: Or Mel Brooks is on, and he is so funny, and you think, "What a wonderful world we live in, that there's a Mel Brooks to go to sleep to."
Luke: Mel Brooks is never on Charlie Rose, and when he is on he's talking about Nazis, and then you go to sleep and you dream about Nazis and they all look like Nathan Lane, and you're creeped out for days.
