#6. WWE's Anonymous General Manager storyline
WWE Chairman Vince McMahon introduced the Anonymous RAW General Manager in mid-2010, and Michael Cole was the spokesperson for all the emails. The presence of the Anonymous RAW General Manager happened through a laptop, and it played into WWE's storylines more often than not.
WWE quietly phased out the Anonymous RAW General Manager a year later in July 2011, with Triple H and John Laurinaitis being used as the two primary authority figures.
Another year had passed, and on RAW 1000, Santino Marrella of all people did an investigation and revealed that Hornswoggle was, in fact, the Anonymous RAW General Manager.
It was undoubtedly an underwhelming payoff after the emphasis WWE had put on the anonymous RAW General Manager for over a year. Former WWE creative writer Kevin Eck revealed that he pushed for Kevin Nash to be in that role, but that didn't work out (more on what played out later).
Strangely, Hornswoggle got the spot only because he joked backstage that he should be the one in the Anonymous GM role, referencing Vince McMahon's "illegitimate child" storyline from a few years before.
Hornswoggle also said that there were plans for him to be a serious "mob-boss" type of character who had a "Napoleon Complex." It would have been interesting to see if WWE pulled that off.
From what we understand, WWE never had any serious or concrete plans for who the GM would be.
