This is the first appearance of Petey, on February 15th 2004, in the second strip published in the Wash Post Magazine. He's changed only slightly; I think I like his hair better here. And below this strip is an Almanac cartoon from maybe ten years ago. See? It all fits together. Someday I'll figure out how every drawing I've ever done is a small piece of a larger picture, and my personality will then be so integrated that I'll be issued a certificate of guaranteed sanity by whoever's in charge of such things. Then I won't know what to do with myself.
I think the Captain Busybody strip just proves that superheroes are impossible to parody, unless the parody takes the form of Herbie or the Tick.
