UPDATE: Comic found! I was totally misremembering this as a three panel comic where thery're in bed. Which explains why I could never find it! https://www.gocomics.com/calvinandhobbes/1992/02/23

Quick question for The Internet.

I seem to remember a Calvin and Hobbes strip where they're in bed and Calvin asks "what's the meaning of life?" Hobbes responds "to eat each other...Goodnight!"

I can't find this anywhere. Was it real strip?
