On Wednesday, the Foo Fighters were performing in Hamburg, Germany. Dave Grohl spotted a fan in the sold-out crowd that was holding up a painting (Which must have been a pleasure for the fans sitting behind him). The artwork was a portrait of Mr. Dave Grohl himself, so the rock god invited the talented artist onstage.
Grohl gave up the mic to the gifted artist and he waxed poetic about the Foo Fighters frontman. After some technical difficulties with a pen, Grohl was given a Sharpie and signed the painting, right on his own forehead. That painting just increased value exponentially.
Dave Grohl everybody, rock god, and all-around good fucking dude.
