Those of you who, like me, adore Calvin and Hobbes would probably like Frazz, as well. In many ways, the two comics are incredibly similar (to the point that some have speculated that Jef Mallet, the artist, is actually Bill Watterson in disguise. Even this conspiracy buff can't buy into that one, though, although Watterson's influence on Mallet is undeniable.) There are numerous literary references throughout the strip, including the fact that one of the characters is named Caulfield (after Holden Caulfield) and dresses up like literary characters for Halloween.
Anyway, check it out if you haven't already.
