The Batman: the Animated Series Test

Batman: the Animated Series. The best superhero cartoon to hit TV in ages. Do you know the difference between Alfred in the episode "On Leather Wings" and other episodes? Do you remember what made Batman hit his head on "Harlequinade"? Do you remember the name of the Riddler's former employer? Can you live up to the mantle? This test is HARD! Only one person has gotten above 80%. No one has gotten a perfect score. This is for hardcore B:TAS fans!
