At the end of the episode, when Abed is talking about "the darkest, most terrible timeline and creating the fake "Evil Goatees", there is writing on the chalkboard in the background, it reads; "Please return all books left in Study Room to the front desk. All special items were turned in at the Student Union BLDG. Have a great weekend.... My bad, see ya tomorrow." There is also an indication of the episode number "Tg 303" in the top right corner.
