Calvinball is the greatest sport in all of comicdom. It’s like quantum physics, if you think you know the rules your wrong!

    “if you think you know the rules you’re wrong” – fixed.

    And I think adding “There are no rules.” in black text in the white semi-circle would add to the look of this.

    But that isn’t true! There ARE rules! They just change!

    Oh, and robotbee is right: there ARE rules. Well, one rule: “you can’t use the same rules twice.”
