Shark jumping

I think the phrase "jump the shark" has probably now jumped the shark itself, but there's really no more appropriate way to describe this:

On the same wave as Geraghty and Hanson today, Rush Limbaugh just called on Al Gore to hand over this prize to "genuine agents of peace: General Petraus, the U.S. military, and its commander-in-chief."

OK, maybe a way to describe it that's just as appropriate is "stark bat-shit raving insane." Do these folks understand how much like Animal Farm they sound?
