Formula 1 racing returned to the U.S. for the first time in five years this season, but that wasn't the only thing worth remembering from the year's 20 races.

As this video from Formula 1 Home illustrates rather artfully through images, video, and a rhymed, rhythmic narration, the 2012 season was actually quite an exciting affair, right down to the wire.

How lucky was Fernando Alonso when Romain Grosjean went skimming over his helmet? How could anyone have guessed Lewis Hamilton's departure to Mercedes? What will Michael Schumacher's legacy be after his struggle to get back on pace with Mercedes upon coming out of retirement? Can Sebastian Vettel and Red Bull fend off so many other talented (and championship-winning) drivers and teams for yet another season?

Many things to ponder. Good thing it's the silly season.
