Mom's Cooking Has a Rat Problem
A character in the game simply named Mom offers you rat pie, rat loaf, and spaghetti with rat sauce, and you can ask if there's anything without so much rat in it. That's a direct lift from Monty Python's Dead Bishop sketch, where Michael Palin's character asks for strawberry tart without so much rat in it. The joke even gets a callback later when a sheriff mentions it being tattooed on the back of your neck.
