What's The Greatest "F*@% Yeah" Moment Of All Time?

We root for heroes who are underdogs, who suffer unimaginable setbacks and misery. But sometimes, we root the hardest for heroes who bounce back and do something incredibly awesome. Philosopher/sage Dave Campbell calls this the "F*@% Yeah" moment. But what's the greatest fist-pumping scene of all time?

Please include a picture, clip, book cover, comics panel or other illustration for your moment of transcendent badassery. And please mention the character, the situation, and why it was so insane. Thanks!
