Here's an April Fools' joke you'll like: Fans of the series Rick and Watch Sex (1994) Part 1Morty have been waiting more than one year, but Adult Swim finally aired a new episode of the show Saturday.

Available to viewers in the U.S. and other "select locations," the Season 3 premiere is set to play on loop until midnight ET and PT as part of the channel's April Fools' prank. Viewers are advised to get their adult sci-fi fix of mad scientist Rick and his grandson Morty while they can.

The show's co-creator, Dan Harmon, teased the stunt Friday night before blasting it on Twitter the following day.

As for UK viewers who were unable to watch the clip, Harmon had only one thing to say. Not kind, but fair.
