20 Best South Park Episodes Ever

6. Imaginationland Episode III (Season 11, Episode 12)

The third and final entry into the Emmy-winning Imaginationland saga is an explosion of pop-culture references and brutal violence, and South Park at its absolute best.

As a potent commentary on the War on Terror it's terrific, but it's the outrageous battle royale of ironic heroes and villains that takes it to the next level, with Jesus fighting a Xenomorph, Popeye punching Darth Maul and the Woodland Christmas Critters exploding Tron Guy's head.

Best Moment: Because Imaginationland allows real people to conjure up anything they can think of, Cartman imagines Kyle enthusiastically sucking his balls (as Kyle was supposed to do for losing a bet about the existence of leprechauns) as the episode's final punchline.
