Listening to the Meltzer post-show, if anyone was curious why the crowd was distracted a couple times during the beginning of the ladder match, it's because a few fans tried to throw streamers into the ring, and they got KICKED OUT. The audience was booing that. A few minutes later they let the fans back in and the crowd started chanting "YES!"
Dave speculated that it was Barclay's that threw them out not knowing the deal with the streamers, and WWE told them to let them back in because streamers are fucking streamers and not anything to get in a tizzy over.
It's hilarious that those were the only streamers in the building tho, and none of them came close to the ring.
