Are two Heads better than one?

Another marvelous freaky moment in the series, if you were paying attention. It's the end of "Prize Fighters," and Jake Morgendorffer is sponsoring a hot dog eating contest to advertise his business. Lots of kids walk up to watch the fun.

Among them is The Head, walking in from the left side of this image. He's coming up behind Bob.

Also walking over is The Head, coming in from the bottom of the screen on the left side.

What the hell is going on here? This school has more mutants than Xavier's Academy. Does this have anything to do with the time The Head's glasses turned black, or when he appeared on a milk carton as a missing kid? Does Shaggy (over on the right side, orange shirt) have anything to do with this?
