Family Guy and The Simpsons premiered Sunday with an epic crossover episode, “The Simpsons Guy,” and not-so-subtly discussed the differences between the two shows through arguments between Homer and Peter Griffin.

Griffins In Springfield

“The Simpsons Guy” found the Griffins stranded in Springfield and staying with the Simpsons.

As expected, not everybody from the two iconic animated families got along. Brian was particularly put off by Santa’s Little Helper – a dog that acts like a dog! And, Marge was confused by Brian’s human-like desire to sit at the table for dinner.

Meanwhile, Lisa wanted to help build Meg’s self-esteem and helped Meg find her talent: the saxophone. And Bart taught Stewie the art of the prank call.

Peter and Homer: Family Guy vs. The Simpsons

Peter and Homer got in a heated argument over which beer was best: The Simpsons’ Duff or Family Guy’s Pawtucket Ale. Of course, “The Simpsons Guy” used the beer as a way to poke fun of how intertwined the two shows have become, with Homer saying Pawtucket Ale tasted exactly like Duff. “It may have been inspired by Duff, but I like to think that it goes in a different direction,” Peter responded.

Peter and Homer continued to make jabs at each other throughout the episode. Peter lashed out at Homer, telling him he hasn’t wanted Duff beer in 13 years, and Homer attacked Peter with Emmy’s. The entire spat ended up in court for copyright infringement.

When the two finally banded together, Homer and Peter decided to try to lure the car thief that left the Griffins stranded in Springfield with a “Free Stolen Car Wash.”
