"In-A-Gadda-Da-Leela" is the second episode of the sixth season of the animated sitcom, Futurama. It originally aired directly after " Rebirth" on June 24, 2010 on Comedy Central. In the episode, Zapp Brannigan and Leela end up on a Garden of Eden-like world after fighting a planet-destroying satellite called V-Giny.
The episode was written by Carolyn Premish, who created the story for the episode with Futurama creator Matt Groening. Dwayne Carey-Hill directed. It features references to Adam and Eve, and Matt Groening's other show, The Simpsons, along with self-parody. The episode received positive reviews from critics.
Notably, "In-A-Gadda-Da-Leela" is the first of several episodes to use a significantly shortened intro sequence this season, and consequently is the first episode in the series not to show a brief clip of a classic cartoon before the opening credits.
