Rick and Morty Season 4 is set to return in May! But let’s not forget what happened on April 1st, 2017, when fans of Samurai Jack were expecting to see the fourth episode of the fifth and final season of Genndy Tartakovsky’s hit animated show. Instead, fans were treated to the season 3 premiere of Rick and Morty, thus bumping the ‘foolish samurai warrior’, in Aku’s words. Though the Rick and Morty trailed dropped March 31st, April Fools Day is a day Adult Swim takes seriously, so their adult animation programming block could be filled with surprises. Perhaps in the form of Dan Harmon and Justin Roiland’s hit animated show.
