THE STUDY GROUP DIVES INTO HISTORY 101 – CHANG RETURNS TO GREENDALE – MALCOLM MCDOWELL GUEST STARS

After losing out in registration for "The History of Ice Cream," the study group begins their European History class with Professor Noel Cornwallis (Malcolm McDowell, "Entourage," "Franklin & Bash").

To make matters worse, the group encounters the return of the arrogant German students from last season, which Jeff (Joel McHale) and Shirley (Yvette Nicole Brown) faced over the foosball table.

Much to Dean Pelton’s (Jim Rash) dismay, Chang (Ken Jeong) makes his return to campus. Chevy Chase, Danny Pudi, Gillian Jacobs, Alison Brie and Donald Glover also star.
