I love how Dilbert and Dogbert are both crazy smart, but Dogbert always seems to come out on top...although you gotta feel for Dilbert sometimes. Poor guy, can't catch a break.
This whole comic seems predicated upon the notion that Dilbert did dumb things from start to finish. It's as though he took somebody else's dumb-drug in order to get the notion to create his own batch, and then he was dumb enough to dip a dart into it and hand it over to Dogbert. Having Dogbert inject more dumb into him seemed superfluous.
