#1 Lousy Rousey
Now, this incident is sure to have gotten some backstage production personnel as well as security (for allowing the sign to get past them) into trouble with Vince. Somehow, a fan right in the third row, in full view of the hard camera, managed to sneak in a sign that read "Lousy Rousey".
The sign wasn't exactly visible throughout the show though. It could first be seen when Ronda Rousey climbed on to the ring apron and a moment later, the sign was in full view when the broadcast switched to the hard camera position (as can be seen above).

Realising the blunder, the broadcast immediately switched to a different camera view and a few minutes later the sign appeared to have been confiscated, as it could not be seen again when the camera panned back!
