Have you seen these if so and so had facebook things going around? One of my favorites from If Star Wars had Facebook:
There's a similar series of If Lord of the Rings had Facebook:
Not quite sure how these were created, but someone should do one for WOW. My suggestion? Start with Jaina. She could say my guildie Shmoopsypoo's favorite line of hers: "But I just wanted to study", then Kael'thas could say "Yeah, I've heard that before", then Arthas could say "She didn't have to study with me Kael'thas". Hahahaha /sigh. I think I need more sleep.
On a side note, Jaina sort of irritates me, but I can't exactly put my finger on why she does. Apparently she may have been named after Jaina Solo, the jedi daughter of Han Solo and Princess Leia (on Jaina's wowwiki page).
