Random bizarreness

Mallard Fillmore really outdoes itself this week with a totally inexplicable series of strips mocking the USDA's redesigned food pyramid. There's little or no indication of what Tinsley's particular problem might be with the redesign, or why he thinks it's a vital enough issue to devote an ENTIRE WEEK--we're just treated to an endless (it certainly FEELS endless) barage of head-scratching non-jokes concerning the alleged...badness...of the new pyramid. Or something. It's very difficult to determine. Has Tinsley finally lost whatever vestigal cognitive function he may have possessed?
