Carrie Underwood and Brad Paisley kicked off the Country Music Awards show with a monologue that included a song about President Donald Trump's tweets.

"He writes little Bob Corker, NFL and kovfe...," Paisley sang, attempting the non-word Trump tweeted earlier this year that went viral and captured the news media attention for several days.

The CMA Awards hosts then had an exchange where they tried out different ways of pronouncing "kovfefe."

Paisley went back to strumming his guitar and singing about the possibility that Trump starts a nuclear war with North Korea' leader Kim Jong Un, who Trump once referred to as "Rocket Man," because of his tweets.

"And it's fun to watch it, that's for sure, until little Rocket Man starts a nuclear war and then maybe next time he'll think before he tweets," he and Underwood sang.
