It's been a while since Jeff Keane (all grown up) has compared his big brother Billy to Jesus. Last time, he managed to humiliate Billy by drawing him standing in cruciform position while wearing a frilly pink dress. This time, Jeff is, on the surface, slightly less cruel; instead of implying that his brother looks ravishing in lace, he merely assaults the poor guy with a brain-cell-destroying pun. It is not a particularly good pun. Actually, none of the puns that appear in The Family Circus are particularly good puns. It does, however, allow Mr. Keane to use his knowledge of medieval philosophy to make Billy look like a jerkwad.
I seriously believe that Jeff Keane had a hard time not drawing a sarcastic halo here. Little Billy is very much a type of Christ in this comic: glowing, surrounded by the Little Lines of Enlightening,* ready to accost the poor unsuspecting world with his revelations about how 2+2=4. Mary and Joseph--er, Bil and Thel--are amazed by their son's raw intelligence, as well, I suspect, by the Little Lines; they are so impressed that Bil just has to say something incredibly stupid.
However, there is a dark side to this portrait. One should certainly aspire to the imitation of Christ, but Billy's smug smile implies that he is very pleased with his own brilliance. Was Christ not humble? Beware, Billy, of the Sin of Pride. To know you are a type of Christ is to prove that you are not a type of Christ. Jeff Keane, by portraying Billy as a self-satisfied Christ-like figure, is saying to his brother, "Billy, you're going to burn in Hell. In Hell, I say. I don't care that you work for Disney. I'm not at all jealous. You are going to weep blood as you boil in the fat of your victims! Want to come over for dinner on Sunday?"**
