One of the side missions in The Fractured But Whole involves an infamous gay fish, which references Season 13, Episode 5 of the South Park TV show titled "Fishsticks." In the episode, the gay fish refers to the famous rapper Kanye West and his inability to understand jokes.
If you play the gay fish side quest, you'll find the Kanye-fish doesn't get the joke at the end of the mission. It's a truly hilarious Easter egg that will leave you breathless.
