Why they fought: The Mountain flipped out after losing a tourney battle to Ser Loras. The Hound jumped in and saved Loras' life (but wasn't fast enough to save that poor decapitated horse).
Winner: King Robert stopped the fight before either Clegane could claim victory, but The Hound impressively held his own against his brother, arguably the most feared fighter in Westeros.
Eddard vs. Jaime
Season 1, Episode 5
Why they fought: Jaime was mad Catelyn took Tyrion hostage. Eddard was mad Jaime had his men killed.

Season 1, Episode 8
Why they fought: Mago challenged Drogo's rule when he allowed Daenerys to protect women from rape: "A Khal who takes orders from a foreign whore is no Khal."
Winner: Drogo, who ripped out Mago's throat with his bare hands and delivered some of his most badass lines of the series. ("The worms will crawl through your lungs!"). Sadly, the wound Mago gave Drogo would later prove fatal.

Why they fought: Qotho was angry about Daenerys bringing in a witch to heal Khal Drogo. Jorah was not about to let someone harm his queen.

Season 2, Episode 10
Why they fought: Qhorin wanted the Wildlings to trust Jon, and believed sacrificing himself was the only way to do it.

Winner: The Hound, despite Beric Dondarrion playing a bit dirty and lighting his sword on fire. "Looks like the Gods likes me more than your butcher's boy," he tells Arya. As for Beric? He was brought back from the dead, so no big deal.

Why they fought: Brienne and the bear were forced to fight by the horrible Locke. Jaime heroically jumped in to the battle to help his friend, who was armed with just a wooden sword.
