One of the best quest lines..EVAR! (spoiler)
There be spoilers, don't read if you don't want to see it.
Trying to get a few quests in to get to 58, and dungeon xp has slowed down considerably at 54/55, so I found this gem near New Kargath.
[spoiler]
You get a quest called The Day that Deathwing Came. Basically, the dwarf tells you the story about how he punched Deathwing in the face, by having you re-enact it. The dwarf is the vehicle, and you're 'driving' him, punching rock elementals, walls, and eventually you get to Deathwing, and you punch him in the face. End of story, or so you think.
Turn that one in, and get this from the gnome next to him: The Day that Deathwing Came: The Real Story. It's the gnome version of the same story, except you shrink the world and find Deathwing in the sun. You burn your hands grabbing him, but you manage to throw Deathwing all the way to Kalimdor, thereby saving Badlands.
Turn that one in, and the orc has this gem (It's Martek the Exiled, from vanilla..I think he was a LW trainer?): The Day that Deathwing Came: What Really Happened. As the orc, you're on your motorcycle, and can only save one of the chicks crowded around you; an orc, a nelf, a human, and a male belf (classic!). I picked the nelf, and he says "I took the night elf, obviously." and you have to ride to where Deathwing is, dodging falling rocks. When you get there the orc says "Oh yea, I forgot my motorcycle could fly, probably should have mentioned that earlier." So you fly up to the cliff where Deathwing is, and there's the Dwarf punching him in the face. The orc says "Hey, this is my story, stop interrupting" or something like that. Here comes a giant gnome walking around, and the orc says "Fine, I won't tell you how I killed Deathwing with a knife."
[/spoiler]
You have to do it once per character, but it was worth it. I tried picking up each chick to see the differences. Pretty damn funny one.
