Yeah. It could also be a case of withholding something for the next season. Like that Cookie song we saw the taping footage of. We won't know if it was scrapped until we get word that it was or until the last episode of the season.
It still could and should have been internet exclusive if they couldn't fit it on the show. There's a good chance that they just didn't put it on the last season, and are waiting, otherwise it would have popped up online by now. It would suck for Tau if they didn't run it even as a viral video, and Kevin would stand to look bad if he couldn't use his pull to get the segment on the show. The dude pretty much does everything on the show now, I'm sure they'd let him speak for that segments behalf.
