Dave Grohlcemented himself as the coolest man in rock n' roll a long time ago, but he still just keeps doing things that prove he's totally chill.
His latest epic endeavour was going onto kids' TV and having an awesome drum battle with Animal from 'The Muppets'.
The former Nirvana drummer and Foo Fighters frontman said he'd "been waiting years for this" as he began to duke it out with the puppet, who once famously had a drum battle with Buddy Rich.
In the end of this epic battle, however, there were no losers. Both conceded defeat but were victorious in our minds.
