Dave Grohl played a prank on Foo Fighters fans in Sweden Tuesday.
The band was performing at Ullevi Stadium in Gothenburg, which is where Grohl broke his leg three years ago. They came out at the start of the show, and before they started playing, a man that looked like Grohl -- holding a guitar, dressed in black with long black hair -- ran on stage. He ventured out to the ramp into the crowd, waved to one side and then fell off the stage.
The prank was quickly revealed when Grohl ran onstage and the band started playing. Check out a video of the prank on the Foos' Facebook page.
