Ep 31. The Best VHS in the World

Mordecai and Rigby are on a mission to find the best VHS tape in the world. They discover that one of their fellow park workers, Benson, has an extensive VHS collection and decide to check it out. However, Benson is reluctant to let them borrow any tapes because they never return them on time.

Undeterred, Mordecai and Rigby are determined to find the tape they're looking for and continue their search. Along the way, they run into various obstacles and distractions, including a group of kids trying to steal Benson's VHS tapes, a video store clerk who tricks them into buying a useless tape, and a strange man who keeps showing up and offering them different tapes.

As they continue their search, Mordecai and Rigby begin to realize that there may not be a "best" VHS tape in the world after all. Instead, they come to appreciate Benson's collection and realize that it's the memories and experiences attached to each tape that make them special.

In the end, Mordecai and Rigby return all of the tapes they borrowed and apologize for their past behavior. Benson forgives them and even lets them borrow his rarest VHS tape, which they watch together in the park. The episode ends with the trio enjoying the tape and reminiscing about their favorite memories from childhood.
