I'm a huge fan of the NBC show "Community" and there's a running joke about how Abed is a bigger fan for the ABC show "Cougar Town." In this scene, Abed gives a long anecdote about how he traveled to the "Cougar Town" set and managed to get into a scene during shooting.
Then I was watching "Cougar Town" last night and...who's that weird guy?
Abed! Nice. Here's more on the episode from ZapIt.
