I don't know how widely Big Nate is syndicated in newspapers but as part of the GoComics stable, I'm guessing it's seen by quite a few people. When I occasionally flip through the criminally misnamed "funny pages," Big Nate is a beacon of mild entertainment, one of a scant few such dim lights in the cold, black, humorless night that is today's newspaper comics section. That is to say, I don't love it, but I'm not physically repulsed by it either. Sometimes I feel something like a smile approaching when I read it.
Not June 19th, though.

Look familiar? It should, assuming you're familiar with one of history's greatest works of literature: Bill Watterson's Calvin and Hobbes. (I understand if you never return after clicking that last link, as a C&H search engine is a transmogrifier that converts spare time into spent time.)

I don't know if the Big Nate strip is a less funny rip-off, a less funny accident, or a less funny homage. But without some clearer nods to its source material (for example, if Peirce's strip had appeared on the anniversary of the C&H strip's original publication date), I'm ruling out homage. It's possible Peirce was channeling Calvin and Hobbes accidentally, not realizing where his oh-so-clever inspiration was coming from, which happens to the best of us (even The Beatles; I'll let my dad elaborate on that one). I hope that's the case.
Either way, this reminded me a lot of my last post about sampling. Sure, everything's stolen, and I bet someone will point out a comedian from the '50s from whom Bill Watterson stole this bit (as a matter of fact, judging by the search engine, Watterson recycled his original strip with slightly enhanced colors four years later...is it stealing if you steal from yourself? As John Fogerty of CCR knows, yes, sometimes; once again, I defer to my dad on this explanation). But it's much less palatable when no personal spin is added, especially when these are two artists using the same exact medium. And it's worse when no explicit credit is given. Cite your sources, Peirce, if that is how your name is really spelled.
Edit, July 3, 2011: Whoops. In the second sentence, I originally called the creator of Big Nate "Leonard Peirce," but his name's actually Lincoln Peirce. I guess the "fool" in the title is me, too! Also, someone has since edited Peirce's Wikipedia page to reflect his job as a cartoonist rather than a cartoon. Looks like I'm making a difference in the world.
