A first Wednesday night for Dave Letterman's CBS "Late Show": His Top Ten list was expanded to Top 12, the number of drivers in NASCAR's Chase for the Nextel Cup. A dozen NASCAR drivers delivered the goods, describing little-known secrets of motorsports:
No. 12. Clint Bowyer: "We've got special mirrors that show objects the size that they actually are."
No. 11. Kevin Harvick: "Sometimes back in the garages there's horseplay with the air hose."
No 10. Jeff Burton: "Between the G-forces and the fumes, I'm loopy most of the season."
No. 9. Kyle Busch: "Switch the `R' and the `C' in `Racing' and you get `Caring.' "
No. 8. Matt Kenseth: "Can hold eight gigs of music on my new iHelmet."
No. 7. Martin Truex Jr.: "In a pinch, checkered flags make a lovely tablecloth."
No. 6. Denny Hamlin: "Two more wins and I get to marry Ashley Judd."
No. 5. Kurt Busch: "You can talk to your car and pretend you're David Hasselhoff."
No. 4. Carl Edwards: "How many people can say their `office' goes 200 miles per hour."
No. 3. Tony Stewart: "Driving fast and starting fights."
No. 2. Jeff Gordon: "It's not one of those sports you have to inject stuff in your butt to be good."
No. 1. Jimmie Johnson: "Unlike most guys, I like it when my wife says, `You're too fast.' "
