Grampy Can Ya Hear Me

During the opening titles, when Maggie pops out of the grocery bag, she is holding a jug of Szechuan sauce. This is probably a reference to another animated show, 'Rick and Morty,' in which they referenced the Szechuan dipping sauce that used to be served at McDonald's.

In the electoral map in Lisa's dream when she is about to be elected president she only has 220 electoral votes while her opponent has 318.
