Discovery, 7 p.m.
One of this summer's best-kept TV secrets, this Canadian-made series is both informative and entertaining. The concept takes viewers behind the scenes of some of the world's busiest locales and workplaces, with earlier episodes filmed at New York's Grand Central Terminal and the Cirque du Soleil production of O at the Bellagio Hotel in Las Vegas. Tonight's episode travels to Washington to focus on the frenetic operations at the District of Columbia Fire and Emergency Medical Services, which handles more than 400 calls each day
CBS, 8 p.m.
Based on a British TV concept, this program is arguably the sneakiest show on television today. The format follows high-end corporate executives as they slip anonymously into the grubby work force of the companies they run. Previous episodes have been filmed among the rank of file of 7-Eleven, Roto-Rooter and the restaurant chain Hooters, but tonight's episode is a change of pace. Cincinnati mayor Mark Mallory goes undercover as a mechanic repairing city vehicles, followed by a stint as a sanitation worker tasked with scraping road kill off the streets.
Friday Night Lights
Global, 9 p.m.
That?s a wrap, y?all. Considered by many critics to be the best drama ever made for network television, Friday Night Lights concludes its fifth and final season tonight. Set in a small, football-mad Texas town, the show stars Kyle Chandler as high-school football coach Eric Taylor, with Connie Britton playing his wife, Tami. In tonight?s closer, Eric and Tami are pondering their future together, while Julie (Aimee Teegarden) considers a marriage proposal from Matt (Zach Gilford). The big story, of course, is the East Dillon Lions playing for the state championship. Go, team.
Desert Car Kings
Discovery, 10 p.m.
My new favourite show. Produced for the U.S. Discovery Channel, this series follows the daily work routine of the father-and-son team of Ron and Jason McClure, who operate Desert Valley Auto Parts on the outskirts of Phoenix, Ariz. Looking for a radiator cap for a 1965 Ford Thunderbird? This is the place to go. The show's appeal stems from the nostalgic factor of the old cars (the McClure compound has more than 10,000 ancient vehicles) and the passion that the McClures put into each episode. Watch them get excited tonight as they try to fully restore a 1950 Studebaker Champion.
AMC, 11 p.m. ET, 8 p.m. PT
