The difference in the Olympics ratings gives some idea about how popular each night of TV watching is.
THIS WEEK IN TV, THE MOST BORING WEEK EVER Again, NBC's lineup this whole week is the Olympics. Monday, ABC has a new High School Musical followed by Bewitched. Tuesday brings a new Primetime: Medical Mysteries to ABC, and Big Brother to CBS. On Wednesday there's a new Greatest American Dog on CBS. Not only are there new episodes of Big Brother and Flashpoint on CBS, but there's NFL Preseason Football: 49ers @ Bears. You can watch Collateral followed by a new 20/20 on ABC, Friday Night Smackdown on The CW, and NFL Preaseon Football: Houston vs Dallas on CBS. ABC would like to offer you Madagascar Saturday night, FOX has America's Most Wanted, and CBS brings you NFL Preseason Football: Pittsburgh vs Minnesota. If you're not interested in the Olympics Closing Ceremonies, there are new episodes of 60 Minutes and Big Brother on CBS.
I looked on imdb for the guys name to see if they said anything about the particular episode of Curb that he was on, and it was the episode where Larry bought pot for his dad. It was the "Car Pool Lane" episode which is the same thing.
