I can think of a good one...there's a half-dozen or so horde, mostly 70s, a 66 or two, in Halaa; we'd just done the Ring of Blood quest and were heading home, Halaa has 0 guards and most of the other Alliance have given up or were corpserunning...me, my twins, and a holy/disc pvp/arena-spec priest pretty much ride into halaa from the north and COMPLETELY FUCKING STEAMROLL every one of them without a single alt dying. They all res'd a few times, even all together and died again...we invite everyone else into the fun now the horde're pancakes on the ground now and we take halaa =D Nothin better than taking out s2/s3 welfare pussies with my raidgeared lead + quest gear alts >D

My most memorable non-boxing one though has to be my Troll rogue around lv34ish, doing the Satyr quests near the alliance town in Desolace; Human Pala shows up, lv40 in plate, and decides he wants the mobs and I can't have any. What followed was quite possibly the most epic battle I've ever fought, both of us burning our cooldowns no less than 4 times over a 20+ minute SINGLE BATTLE; he bubbled alot, I was subtlety so I was vanishing/blinding/sapping like nuts, we both potted a bunch of times, it was freakin awesome. Eventually he fucked up, I forget how, or just gave up one, and I won; I was friggin ecstatic to beat a 40 in plate at 34 with piddly little daggers :p He had the decency to not get pissed after that fight and he res'd, we both continued to quest peacefully after that lol(And he's probably why Paladins are my easiest kills on both of my Rogues...I NEVER lose to a pala in a 1v1 lol)
