Did anyone catch the beginning of the race when Kenseth and Petty got into each other? They replayed the incident, then showed it from inside of Kenseth's car. Upon impact, you hear Kenseth say "What the f*** was that?" Then, there was dead silence for about 30 seconds. Finally, one of the commentators says, "We sincerely apologize for the language there..."
Apparently, the sensors were picking their nose or something.
