20 Celebrities You Didn't Know Appeared In Rick And Morty

First Appeared In Season 4 Episode 3 - Mortynight Run

Jemaine Clements shot to stardom after appearing in the Grammy-winning series, Flight of the Conchords. Ever since he found fame, the Kiwi singer/writer/director/actor kept himself busy with projects including Men In Black 3, Legion, and his directorial debut, What We Do in the Shadows.

He's also done a lot of voiceover work including Moana, The Lego Batman Movie, Rio, and, of course, Rick & Morty. In the episode, Mortynight Run, Clement portrays a sentient gas cloud, who intends to wipe out all carbon-based lifeforms. Even though he is nameless, Rick refers to him as 'Fart'. Oblivious of the word's connotations, the gaseous entity says he likes the way 'Fart' sounds and embraces it as his name, much to Rick's amusement.
