I am pretty sure Calvin never peed or prayed in any of the comics. I’m fascinated by the country-wide obsession with his bodily fluids or his apparently newfound faith. Not to mention the copyright violation all of these people are encouraging. (Have you noticed Watterson never licensed the images for merchandising?)
Today I followed a large Chevy truck with a Calvin urinating sticker on the back, and hanging from the trailer hitch: two silver balls. Aw yeah.
