Universes collide as "Adventure Time" heroes Finn (Jeremy Shada) and Jake (John DiMaggio) appear in this week's episode of "Futurama."

The episode, "Leela and the Genestalk," airs Wednesday night on Comedy Central, taking the Planet Express Crew that brings them into a fateful counter with a pair of adventurers. What will happen when John DiMaggio's Bender meets John DiMaggio's Jake?

This isn't the first time a Matt Groening-created series has leaped into another animated universe: we'll always remember (and love) the early "Simpsons"/"The Critic" crossover as well as a brief appearance by Hank Hill later in the series' run.

See "Leela and the Genestalk" Wednesday at 10 on Comedy Central.
