By far the entry on this site with the most hits is the one about Calvin & Hobbes‘ last strip. It also gets a lot of comments like “That’s not the real last strip!” from people people who surf in there and just read the title and the strip in the entry without reading any of the actual entry. Sigh. Internet nitwits, what can you do?
If you’re a fan of C&H, though, probably the closest you’ll ever get to a fix of new strips comes from a webcomic called Pants are Overrated (now apparently defunct), which did an occasional strip about Calvin all grown up, but really more about his daughter Bacon (!) who hooks up with Hobbes in much the same way Calvin did.
You can read the four strips they did here:
Good stuff!
