Last night's episode of Community provided a mystery for Jeff and Annie to figure out: Jeff lies about a 1-credit course and a man with a "Professor Professorson" ID comes to the rescue. Kinda. Brace yourselves for guns a 'blazin!

All you really need to know in order for this video of highlights to make sense is that the dean caught Jeff trying to get credit for a fake class. As Jeff is trying to explain himself, a random staff member shows up with credentials. One problem: he is not who he says he is.

In other news, Troy and Abed built a gigantic fort inside of the school. It was a major hit... until it went too mainstream and they had to shut it down.
