Bar none, MUTTS is my favorite comic strip. It is funny and poignient at the same time.  Whenever I see Mooch arch his eyebrow, I think that McDonnell has been influenced by Geo. MacManus' Maggie; more than that, it's the way he draws all the faces a-la Bringing Up Father (also, coincidentally?, a King Features syndicated strip.)

Were I on a desert island and could only have one comic strip, and one adventure strip, they'd be Mutts and The Phantom (speak of a guilty pleasure!).
