Basically just a joke on why the pizza chain (I think it’s called papa Murphys?) is so popular when they don’t even cook your pizza for you. They just make you a custom frozen one (I have heard it’s actually pretty good though). The joke is basically just a callback to the time there was a pages long debate on the legitimacy of such a practice.
The Papa Murphy’s near my house went out of business. Went over there one day to get a pizza and the whole store was gutted with the sign missing.
I guess it wasn’t popular enough.
