"Pierrot Le Fou" was a post-modernist French film from 1965.
The entire episode is a tribute to Batman: The Animated Series. The villain
himself is an amalgamation of The Joker and Penguin. His look and weaponry
is very like the Penguin's, but his insanity and the setting for his showdown
(an amusement park) is pretty much straight out of a Joker episode.
"Spaceland" is a reference to Disney Land.
If you notice any references that I missed, I would appreciate
it if you e-mail me.
