On the day they made an appearance on New York Live and the Today Show, the group also did an interview for Entertainment Tonight, which was just posted on Yahoo.
With thanks to Alison Brie Source I was able to get these videos, so thank you!
Unfortunately I cannot embed the video, so you can head to their website on Yahoo to watch the video. I have however made screencaps.

For the next video, it was done by US Weekly and the cast played a game of re-enacting previous storylines that each character had. You can find the video below, and screencaps linked.
