Calvin and Hobbes by Bill Watterson for May 09, 1995
Transcript:
Calvin: How come grown-ups don't go out to play? Dad: Grown-ups can only justify playing outside by calling it exercise, doing it when they'd rather not, and keeping records to quantify their performance. Calvin: That sounds like a job. Dad: ...except you don't get paid. Calvin: So play is worse than work? Dad: Being grown-up is tough.
Good answer.
