New this month Continuity mistake: At one point earlier in the episode, Elroy mentions that there are two baby birds in the nest that needs to be moved. Later, after the nest is moved, Abed mentions that there are three baby birds - two died and one survived.
Other mistake: When we see the Dean's phone contacts, they're suppose to be in alphabetical order, but "Aisha" comes after "Andres" and before "Annie." It should be before "Andres." And "Albino?" is after "Freckles."
