Another series with a strong track record of excellent Halloween episodes (Satan's Halloween Party is another must-see), South Park did some of its best work early on with 1998's "Spooky Fish." Presented in so-called "Spooky Vision" (which consisted of pictures of Barbara Streisand on both sides of the screen), the episode unleashes characters from an evil, parallel universe, including a murderous goldfish and a bearded, creepily nice iteration of Cartman. "Spooky Fish" also features a then-timely treatment of the word "hella," the hot new slang sweeping the nation at the time. How quaint.
