Dave Grohl strikes again. This time, the coolest dude in the music biz invited a fan who created a portrait of him to join Foo Fighters onstage in Germany.

The understandably emotional fan addressed the crowd stating, "I just want to tell you guys I’ve dreamed of this moment a very, very long time, and you think it never comes true, but this time it came true."

Grohl then asked for a Sharpie and proceeded to sign the portrait before directing the fan to the side of the stage. The band then broke in to "Big Me", which Grohl sent out to "the crazy motherf—er with the picture."
