Jimmie Johnson brings the truthiness to the Colbert ReportJay BusbeeFrom the MarblesDecember 6, 2011Jimmie Johnson ventured into the unfamiliar (for NASCAR) terrain of The Colbert Report on Monday night, and acquitted himself and his sport quite well. If you're not familiar with Colbert, it can be an acquired taste, but remember: this is a comedy show.A few notes: check Johnson's reaction when Colbert asks if "there's any doping" in NASCAR; you can almost see the word "Mayfield" flash across his forehead. And Johnson gives us the not-for-the-queasy reason why some drivers pour water on themselves in Victory Lane. Plus, check the move Johnson puts on Colbert to get him loose in the final turn of the office-chair race. Good stuff.
