There's no explaining Flaming Carrot, only experiencing it. Carrot combines the charming childlike adventure of Madman with the fists-up, guns-drawn mayhem of Sam & Max (with buxom babes worthy of Al Capp), but before either existed! To call it Surrealist is, I think, charitable: there is a clear plot, FC is dependable in his strangeness and behaviour, and many characters do make return visits reflective of their previous conduct. So, not Surrealism, but truly damn strange. Burden's art is a suitable match for the stories, as it ranges between just-decent to what-the-hell-is-that-supposed-to-be.
This volume collects early stories from Cerebus, Aardvark-Vanaheim 3D, something called Anything Goes, and the first three issues of Flaming Carrot Comics. There is a new, illustrated all-text story here as well.
I truly wouldn't recommend Flaming Carrot to just anyone, but it's definitely required reading for the strange of heart.
