Explicit rants from Kurt and Kyle Busch highlight best NASCAR in-car audio this season

Kurt Busch may have won the Daytona 500 to kick off the 2017 Monster Energy NASCAR Cup Series season but just two races later at Las Vegas Motor Speedway he was very frustrated with his crew.

The No. 41 driver thought he was told to pit with the leaders but crew chief Tony Gibson said to stay on the track for positioning. It was one of the many back-and-forths between Busch and his team which led to Gibson telling hisdriver to "quit being a smartass and drive."

The elder Busch brother wasn't the only one who needs to donate to the swear jar. Kyle Busch was irate with Ricky Stenhouse Jr. at Martinsvilleat the end of Stage 2. Stenhouse smacked into the No. 18 in order tostay on the lead lap. Stenhouse’s tap also allowed Chase Elliot to dive to the inside of Kyle Busch’s car to win thestage and take aplayoff point away from him.

“Hahaha f— the No. 17, Oh my (expletive) what a (expletive)," Busch said on the team's radio. "We got a left-front rub, we got af—left-rear rub, we got every (expletive) rub because I got thes— beat out of me for no f— reason."
