Calvin and Hobbes by Bill Watterson for June 22, 1990
Transcript:
Calvin: Ok, next we'll race to that tree over there. Hobbes: This race will determine the championship of the universe. Calvin: Oh...wait. How long have we been out here? Hobbes: I dunno. An hour maybe. Calvin: Really? Geez. Where does the time go?! Hang on, I'll be right back. I'm not having fun!
He nearly forgot he was angry, and definitely not having fun.
