Calvin and Hobbes by Bill Watterson for March 12, 1990
Mom: Do you...I mean, does Hobbes want any tuna fish this week? Calvin: No, Hobbes stopped eating canned tuna. You know, they kill dolphins to get it. Mom: OK, I'll put it back. So what does Hobbes like now instead? Calvin: Fresh swordfish steaks. He likes them grilled outside. Mom: Mm-hmm. How about peanut butter?
