Community is possibly one of the only TV shows that could rival the plethora and richness of Arrested Developments guest stars. Betty White was easily one of the funniest (and most delightfully surprising), as perfectly shown in her unorthodox teaching methods of anthropology and subsequent attack upon Jeff, as well as singing the 101 rap with Troy and Abed. Other hilarious highlights include Jack Blacks creepy Buddy, Michael K. Williams angry Biology professor/ex-inmate, David Nehers whiny war veteran Todd and John Goodmans manipulative Vice Dean. With such a huge range of famous actors popping up unexpectedly throughout the whole series, this adds extra excitement to a first viewing, and it also begs the question of who could add to the comedy gold next season.
