Rick and Morty made a strong return with Season 4, Episode 6, which is Dave's favorite episode of the season so far. Never Ricking Morty has an overall framing device of the train for various tales told within.
Dave breaks down the framing of the entire episode, in which Rick and Morty bought a story train from the Citadel of Ricks. Within the story train exists a universe where the story of Rick and Morty is set on metaphorical and physical wheels. There were also plenty of Easter eggs and references in this episode, including Tammy, Bird Person, Evil Morty, Snowball, Meeseeks, a cameo from Paul Giamatti, and more.
