'Rick & Morty' has got to be one of the most insane, original and funny TV series out there.

Created by Justin Roiland and Dan Harmon, 'Rick & Morty' follows the misadventures of Rick and his worrisome grandson Morty. Rick is a cynical, genius scientist whose schemes place tension on his daughter Beth's marriage to Jeff. Morty's teenage sister Summer often gets caught up in the middle.

Debuting in 2013 with 31 episodes across three seasons, the adult animation series has managed to gather quite a following over the years. With episodes that parody the likes of 'Jurassic Park', 'The Simpsons' and 'Inception', and nihilistic outlook, it can break your heart and make you cry.

Everyone has their favourite episodes and these are our top 5. The show is so subjective that our selection obviously won't please everyone. As a compromise, we've decided to let you can change the ranking as you please.

There's no word yet on when Season 4 of the show will arrive on Adult Swim. Last month, a crytic teaser dropped on 'Rick and Morty' social channels. Fans asked/demanded to be told when new episodes are coming as a result of it.

Previously, it was reported that the show has been renewed for 70 more episodes.

Writer and producer Ryan Ridley previously said the new season of 'Rick and Morty' could arrive late 2019. Here's hoping we see it before the end of this year.
