“Rick and Morty” is no stranger to April Fool’s Day fun. In 2017 the show surprised fans by premiering its third season on April 1.

In 2018, the show followed it up with an 11-minute tribute by Australian animator Michael Cusack reimagining the show as a Down Under adventure.

Earlier this week, “Rick and Morty” premiered the first trailer for season 5, which will land on June 20.
