One of the surprise treats that slipped out online on April Fools Day was a new episode of Adult Swim's animated series Rick and Morty. It was also announced during the streaming that was looped throughout the day that the rest of the third series would air this summer. 

The series follows the antics of mad scientist Rick Sanchez and his grandson Morty, who divide their time between family life and interdimensional adventures.
