In just two short weeks, TNT will be taking over the NASCAR broadcasting duties for six weeks -- adios, Digger -- and as part of that, they'll be running weekly prerace "Wally's World" segments featuring driver/analyst Wally Dallenbach. Earlier this week, the fine folks at TNT invited me down to watch the filming of these segments, and I came away with one overriding message: if there's anybody who works less than bloggers, it's on-air talent.

Nah, kidding. I'm sure Wally and his compatriots do plenty of behind-the-scenes work, but as I watched them film two scenes, his total worktime was perhaps three minutes per hour. Still, he made those minutes count, believe me.

But to back up. TNT gets six races this year, and although they start with the stinker that is Pocono, they'll also have Michigan,Sonoma, Loudon, Daytona and Chicago. And for each race, they'll have a whole host of virtual-reality segments where Dallenbach walks in among the cars.

The ramp he's standing on there simulates the track's banking, and he'll be merged with the cars in post-production. If you look behind the cat holding the big white rectangle, you can see the outline of a cardboard car; that's set on the ramp in the exact position that the cars are in whatever freeze-frame Dallenbach will walk through. In this case, it was the famed Keselowski-Edwards spin from Talladega, a segment that will be used when Daytona comes around. Wally walked around the back of Keselowski's car to talk about how the accident happened, and a few minutes later, set up to "duck" Edwards' car as it came flying overhead.

Want to simulate what it's like to be on a sound stage? Okay, here you go. Turn on your television. Put it on a show you want to watch. Watch it for five seconds. Pause it. Go clean the house for 30 minutes. Watch for another five seconds. Repeat ad infinitum, with occasional stops at the buffet for eats.

They wouldn't let me sneak into the background for a cameo, which is probably for the best. Even so, it should be an interesting addition to the NASCAR technological array. Here's hoping that it's enough to help spur the interest in the sport that's been lacking so far this year.
