Foo Fighters is one of those rock bands that will always be in the news. Sometimes, because their lead singer Dave Grohl ends up falling off the stage and breaking his foot, sometimes it's because they do killer improvs and mesmerize the crowd but mostly it's because they're supremely awesome .

Recently, their awesomeness hit the news again, because an injured Dave Grohl let a random dude from the audience play drums for one of their iconic songs . All because the guy was holding a sign saying "It's my birthday. Can I play drums?"

Grohl called him up on the stage and gave him the shortest and most effective pep-talk ever. "You better not fucking suck!", he screamed.

See how it turned out.
