If you're able to hear a turn of phrase as wickedly twisted and strange as "purple Valley Girl-accented space cloud obsessed with her hot body" or "rainbow-colored unicorn that's fluent in Korean" without raising at least one eyebrow, then you're already a fan of Cartoon Network's wildly subversive breakout animated hit, Adventure Time.

Spare yourself the embarrassment of making up an elaborate backstory about children you don't actually have—you're hardly the only grown-up watching.

After being on the air for a little more than two years, Adventure Time has amassed a super-passionate fan base of kids and adults—including loads of famous ones—who are drawn to the show's eye-popping visuals, imaginative storytelling and off-kilter humor. Inspired by creator Pendleton Ward's childhood obsession with Dungeons & Dragons, the show centers around Finn, an ever-courageous hero in the throes of adolescence, and his best friend Jake, an elasticized, shapeshifting dog, as they traverse the Land of Ooo and quench their undying thirst for quests and adventure.
