Mike Mendel
The Season 4 finale, “Star Mort Rickturn of the Jerri,” paid homage to the late, great Mike Mendel. You can see an animated version of Mendel with his dog. He’s famous for his work on The Simpsons as well as Rick and Morty. He passed away on September 22, 2019 at age 54 of natural causes.
Mendel served as a producer on Rick and Morty since its inception, and is even credited posthumously for producing current episodes of the series. Justin Roiland and Dan Harmon decided to have the aforementioned Season 4 finale dedicated in Mike Mendel’s memory. It’s a lovely and touching tribute to his work on the show.
