If you ever start to doubt the coolness of Dave Grohl and the Foo Fighters, just come back to this video. I know the fans at this show in Chile will always remember this moment.

As you'll see in the video below, these fans know and love the Foo Fighters. They continue to sing along with Dave, sometimes before he even starts to sing. So during a break between songs, the Chilean fans starting a "soccer-esque" chant, which kind of halted the show. What Dave and the band did next was pure awesomeness.

Check out the video to see what I'm talking about. There is a bit of adult language, but what do you expect, it's a friggin' rock show.
