7. Curriculum Unavailable (S3, E19)
Another episode from season 3. Curriculum Unavailable dealt with the fallout the study group faced after being expelled from community college. Abed suffers the most, and is told to go see a psychiatrist. The study group gang knows that Abed won't see a doctor on his own, so they volunteer to go together. This episode is full of jokes and one-liners. Blink and you would have missed a few. The plot delves into a lot of flashbacks and even ventures into questioning the reality of the situation the gang currently finds themselves in. In the end, the psychiatrist is found out to be a phony and looking to confuse the group. This is when things start to look up again.
Highlight: Greendale asylum and the study group's shared psychosis
