In one of the strangest races in recent memory, it'd be tough to pick a signature image, but one of the most bizarre had to be the sight of Kyle Busch's tire rolling down the track ... without the rest of the 18 car attached.
A late-race wreck collected both Busch and Matt Kenseth, effectively ending the Chase hopes for both. Somehow in the ensuing pit-road chaos, as Busch's team attempted to get him recovered and back onto the track, someone forgot to tighten a few, or any, lug nuts, and the left front tire spun right off the 18's axle.
And, of course, the humor ensued. The tire stayed on the lead lap, the tire gets bonus points, the tire could finish ahead of Junior, et cetera et cetera. But you can forgive Busch for not laughing, as another season in which he posted the most regular-season wins on the circuit (tied, this time, with Kevin Harvick) came apart in the Chase.
