Foo Fighters Launch Countdown Clock for Unknown Event

The Foo Fighters have launched a website with a mysterious countdown clock, and nobody really knows what it's counting down to.

Some fans are speculating that the countdown is a teaser for a second season of the Foo Fighters' documentary HBO series Sonic Highways, while others posit that it is a countdown until the day frontman Dave Grohl's cast is removed.

Either way, the countdown ends on November 23, and knowing Dave Grohl, this mysterious event could be almost anything.
