On tonight’s episode of Community (NBC, 8 p.m.), Michael K. Williams, a.k.a. Prof. Kane, gives his biology students their first assignment: Construct a terrarium, which is sort of like the D-word. (Diorama.) Will our study group be happy with this, or their assigned lab partners? They won’t. Will Prof. Kane take you on a figurative field trip to Legoland? He will. Check out this exclusive clip below, which is supplemented with a scene that provides relief for those who’d rather not leave their comfort zones.
