I drew this YEARS ago, and in fact forgot it existed it until I was going through some old backup CDs. It's my little attempt at doing a "Far Side" type of comic (boy, do I miss the Far Side!).
If you're familiar with the "Planet of the Apes" movies then you might get a little chuckle out of it. If you're not familiar with them, then push yourself away from the magic computin' box and go watch them (the originals, not the *shudder* remake)!
It was probably drawn with pencil, inked, then scanned into Photoshop where gray tones were added. I think that's supposed to be my attempt at a "kewl" signature at the lower right. Either that or a spider crawled onto the scanner bed.
