Throw It In: During Noah's interrupted Livestream, he calls himself "Adam" (the actor's real name, Adam Rosner); when people in the stream notice, he explains that he's been calling the cops about disturbances so much he's had to start using fake names to get them to respond. Also, according to Word of God in the Media Meltdown video, the knocking itself is unscripted: a friend who lived nearby was watching the livestream and decided to play a practical joke.
The 11/11/12 livestream was supposed to play the INTERCEPTION video at 11:15PM, but due to technical difficulties that didn't happen. The video was then supposed to play when Noah was off-camera, but due to an error on the Livestream's side only the audio of the video played. Word of God has declared he'll use a different Livestream host from now on).
