The Season 1 episode, “Rick Potion #9,” is a reference to the 1992 film, Love Potion #9. Rick creates a love potion for Morty’s school dance. Morty wants to attract his crush, Jessica. Unfortunately, the serum commingles with the flu and spurs a sickly epidemic. You know, normal stuff.
Now, movie buffs might’ve noticed how “Rick Potion #9” bears a resemblance in plot to the aforementioned movie’s premise. For starters, Rick has to create a potion that ensures that whoever comes in contact with Morty will be infatuated with him. Meanwhile, the film features two scientists who concoct something similar, but only on people who hear them talk.
