Remember when Will Ferrell and Chad Smith went at each other? That was nothing.

Will Ferrell and Chad Smith, long rumored to have been separated at birth, started talking smack at each other once and the end result was a mammoth drum competition held on the Tonight Show with Jimmy Fallon.

Unknown to many though, another bitter rivalry has been quietly simmering for years. Foo Fighters leader Dave Grohl has long held a grudge against a rival drummer and one night, in a secret location, the two masters met in an epic showdown.

The Earps and the Clantons? Vader Vs. Kenobi? Rousey and Holm? They were amateurs, kids horsing around.

Grohl and his nemesis, Animal, fought a truly epic battle.
