Calvin and Hobbes by Bill Watterson for October 01, 1991
Transcript:
Hobbes: Making a sign? Calvin: I'm declaring the creek back the woods "Calvin's Creek". When you discover something. You're allowed to name it and put up a sign. Hobbes: But suppose you didn't discover that creek. Calvin: Of course I did! Nobody ELSE has a sign there, right?
I searched Google Maps. There’s a Calvin’s Creek in California. I couldn’t find a Hobbes Creek, but there is a Hobbs Creek (no E) in Wyoming.
