Frankie's cell phone contact list includes former Secretary of State Condolezza Rice. Annie's list includes "That Guy with the Abs," possible reference to Jeff's use of descriptions rather than names for the women he has listed on his cell phone.
This is the 100th episode of the series.
Some of the entries in Dean Pelton's cell phone contact list are "Gobi Nadir" (Abed's father), a double entry for Ben Chang, "Richie or Carl" (the school board members), "Nurse Jackie" (possibly a reference to Nurse Jackie (2009)), "Britta (ugh)", and "Pierce-Deceased :(".
Vicki and Dave's dialogue as they enter the crisis center reflects their position as recurring characters with occasional dialogue. Dave mentions that he's being "called in to do more stuff," while Vicki laments that they'll be lucky to get three words out, just as she is cut off by the main cast.
The scandal City College outlines in their negative ad actually happened at Trinity Southern University of Texas in 2004: a cat named Colby Nolan was granted an MBA from the school as part of an investigation to expose it as a diploma mill.
