In the fourth season (without creator Dan Harmon's involvement), the main cast were given more freedom to improvise.

Each episode ends with a credit as "A Dan Harmon/Russo Brothers _________". The last word(s) include "Fiasco", "Parade of Tears", "Diorama", "Bridal Shower" and "Tantrum".

The character of Abed is based on a real person also named Abed: Abed Gheith, who played a little role in series.
