Was it your favorite philosopher who recommended...?

I was hanging out with three of my favorite famous philosophers the other day, watching the Super Bowl. Two are already dead, but hey, Super Bowl. Everyone decided they wanted pizza, but we couldn't agree on toppings.

"Hey, so what toppings most conform to the ideal pizza?" I asked, "and what would that mean?"

They all groaned, annoyed. "No shop talk!" they insisted. "We're trying to relax here!"
