... and in this case, by "they," I mean, "Brooke McEldowney." First, read the comments here (it'll take you a while--it's quite an active board; look for any of the comments regarding the placement of Luciano's foot in relation to Inky's posture.

ETA: If you're at all interested in the artistry of comics, you need to be reading Mr. McEldowney's work: both Pibgorn and 9 Chickweed Lane. The man is a master.
ETA2: Mr. McEldowney himself showed up in today's comments for Pibgorn!!! Sa-weet!
(And, among other things, announced that he's establishing a blog for 9 Chickweed Lane at http://chickweedcafe.blogspot.com)
