We're not supposed to use logic here guys. It's simple: they had no idea on who the GM should be this week, or decided to remind us of their brilliant Anonymous GM idea. OK, they're complete idiots, but I think they noticed that the idea was completely discontinued and ignored when HHH took over, so they tought, hey, while he's running the show tonight, let's reveal who he is just so we can say we did! Of course, Hornswoggle was never supposed to be the GM when he ran the shows. They never planned to pay off that angle last night. They just used the GM and had to take a comedy exit to the whole thing because nothing could be serious and it couldn't be a relevant person or anything. That's it.
