Didn't some show already do this joke?
The fact is that as a medium, comic books just aren't packing the punch they once did. (wizbenny brought that fact up recently here http://www.i-mockery.com/forum/showt...php?t=69704778
) Webcomics, trade paperbacks, and just plain less and less interest every day are hurting monthly comic books as a whole. When you start selling less, you create less as a result, then to cut losses, you charge more per unit. It is a basic iron law of business.
