Justice League: 18 Easter Eggs & References We Already Know

9. Rick And Morty

Clearly someone at Warner Bros is a big fan of great cartoons. In the background of The Flash's den, one of the screens is showing an episode of cult animation Rick & Morty.

Specifically, it's Season 1, Episode 9, Something Ricked This Way Comes, in which Rick becomes unhappy with Summer's job working in a shop owned by the Devil, obviously and he and Morty travel to Pluto to uncover a plot to mine its core and kill it. It ends, as you'd expect with a juiced up Rick and Summer beating down on the Devil.
