Linus Van Pelt (right) believes in a deity called The Great Pumpkin. It’s like a Santa for Halloween. He also has tremendous sympathy for pumpkins in general and hates seeing them turned into jack-o-lanterns.
When you make up your own religion you can set the rules to be whatever you want, including refusing to eat pumpkin pie
Surely, he could just say “I don’t like pumpkin pie”,
I mean, how many people you know eat it outside of thanksgiving? If it’s only good ~month and then not good the rest of the year, you should accept that pumpkin pie is not good, and just make two Apple Pies.
(Okay so maybe I have this argument with my extended family every year. FWIW, it’s the texture. It freaks me out.)
