Memorable PvP Moments?

While out hunting with my undead rogue on the WoW Insider server today, I came across a Night Elf Warrior, several levels higher than me, in the process of ganking a lowly level 10 Priest, and his friend, who had already fallen. They had put up a good fight, taking about half the warrior's health, but the fight was almost over when I decided to step in at the last minute to see if I could do any good.

I figured that, even with half his health, he would take me down as well without much trouble, but to my surprise, I got a couple of lucky criticals in, and with the help of a handy health potion, actually brought him down. I can't tell you how richly satisfying that kill was was, and it got me to wondering...

Have you ever had any PvP moments in the game that were memorable for one reason or another? Ones that made you want to stand up & cheer, or ones so embarrassi! ng (like being killed by a rogue 10 levels lower than you) that you wanted to cringe? Let us hear about 'em; everybody loves a good adventure story...or a good tragedy.
