The first one is deep and meta with viewer becoming character:
There are a few episodes I missed and this was one of them. After watching the scene, I want to see the rest of the episode.
Apparently, the character Abed does appear in the show Cougar Town, but as himself.
The last video is full of bloopers. It shows the funny and geeky pair Abed and Troy, played by Donald Glover. Together they are cool geeks though. :)
I am also a fan of Batman so I enjoyed the video even more.
Do you watch Community? =)
