Yes, it's fake. Yes, it's a parody. Yes, it's really good.

One day we will all tell our grandkids harrowing stories of The Tweet Wars, those few days in late November / early December 2013 when it seemed like every day there was another bloody battle conducted entirely via tweets and favs, and then when the smoke cleared and we surveyed the wreckage, we found out they were all fake.

Including Diane in 7A, the airplane note-passing war that was live-tweeted on Thanksgiving to wild popularity, and then the Internet gradually teased out that it was probably faked to grab some publicity for Elan Gale, its reality TV producing author. Even before the authenticity was being questioned, the content of the fake notes being passed made it hard to figure out who to root for in the one-sided tale. Gale described the kind of entitled passenger we've all encountered and silently loathed. But in his purported retaliation, Gale came off as unnecessarily hostile and bullying, especially with the infamous "Eat my dick" line, which doesn't do a lot to elevate one's position in a battle of social mores.
