There's no sound for about 95% of the video. You can tell that there should be something there, and you hear a sort of ambient static for most of the time, but other than the intro and a clip between 3:30 and 4:15, no sound. Hope someone can fix it, because I was looking forward to the outtakes.
Sound's working now. Thank you, whoever fixed it.
For the record, this is the short version of the blooper reel. There's a longer one going on Youtube someday with the rest of the season, it's about 12 minutes.
