Pop culture references are like a giant communal joke that everybody's in on. Memes are created and passed around, providing laughter and amusement for all. Marapets is no exception to this, having paid homage to varied elements of pop culture. From the obvious to the obscure, these layers of Mara-joke have something for everyone.
Unless the joke is otherwise explained, reference links will take you to the related Wikipedia/Fandom page.
