The Foo Fighter’s played a surprise show in California last week. After the show, Foo’s and friends ended up at the bar where good guy Dave Grohl picked up the tab. Instead of just paying the customary gratitude of 15% though, Dave instead decided to “tip the bill,” turning a $333 bar tab, into $666.

Whether or not Dave thought it would be funny to pay a “666” bill is not known. What we do know, is that Dave Grohl continues to prove why he’s the coolest dude in rock ‘n roll.
