Tony Stewart may have won Sunday's race at Dover, but that didn't stop him from being extremely "pissed off."
It wasn't because of another driver, or anything that happened on track for that matter. So what exactly got under Smoke's skin?
Veteran NASCAR reporter, Bob Pockrass.
Pockrass posed a question to Stewart during the post-race press conference regarding Stewart-Haas Racing rumors swirling around the garage.
"Obviously during the last few months, there are lots of rumors about your team and possible changes," Pockrass said.
Stewart wasn't having any of what Pockrass was dishing out and quickly interrupted.
"You guys started all that crap. You guys need to come talk to us because we've never discussed any of this crap that's been going around here that's been a huge distraction."
Stewart continued to voice his displeasure towards the media for over two minutes, holding nothing back.
But in typical Stewart fashion, he ended his rant with a fairly nice gesture, saying he would "try to cheer up" before answering Diego Mejia's question.
Think back to Fontana earlier in the season when Stewart went off on a tirade directed at Joey Logano, vowing to "bust his ass." Smoke wrapped up his rant by taking a quick moment to thank Steve Byrnes for the interview.
