When then Illinois governor Rod Blagojevich decided to forgo his own impeachment hearing to ride the media train up and down the dial, I figured it would last one or two, maybe three days tops.

Then a few nights ago, Blagojevich and his hair appeared on The Late Show with David Letterman to clear his name, which is hard to ask people to do when they can't even say it without spraining their tongue.

Blagojevich's appearance on Letterman crossed a line that shouldn't even had to have been drawn for him. And now, he must be stopped.

First off, the man has every right to defend himself, both before the state Senate, in the courts and throughout the public eyeball. This isn't a legal cry for help or a request to change the entire U.S. Constitution to keep one more ego off of the airwaves. If the man wants to go on TV and proclaim his innocence until his face goes from red to blue, then let him.

But there is such a thing as overkill and the prospect of Letterman letting the man sit on his couch ahead of comedy legend Steve Martin seemed like the man was just trying to infect as many people as he could before the noose couldn't be tightened any further. He had gone from the morning and daytime talk show circuit to late night television. Hey all you insomniacs and alcoholics out there, be sure to drop me a line if Blagojevich appears on a ShamWow! infomercial at 3:30 a.m. or an episode of The Wiggles just after sunrise.

Thankfully, Letterman did his homework and didn't do the kind of softball interviews he had to face during his initial interviews. The guy still has an impression of Geraldo Rivera's mustache on his butt.

Letterman actually nailed the guy pretty hard on things other than his lack of an effective hair care regime. He called him on his undying claims that his civil rights have been violated by the Senate when those rights only apply to his criminal proceedings. He called him on his claims that he's being targeted because he wanted to raise the state's income taxes or help bring cheaper Canadian drugs to his state. And yes, he even called hm on his hair. But cut the guy a break. It's like the mole on the Mole's face from Austin Powers. The only way to keep from looking at it is to go Oedipus on your own eyes.

It was such an unnecessary moment in TV history that even Letterman himself asked at the top of the show, "What are you doing here?" But now that it's past and locked away in our unconscious memories, it's time for Blagojevich to move on. He should take all that time and energy that he's building up to clear his name and put it in his actual trial whether his innocence is genuine or not. TV World needs to impeach Blagojevich from their bodies the same way the Senate did last week, unless such a hearing would prompt the human hairpiece to go on another whirlwind tour proclaiming how his civil rights have been violated because he can't call The View to testify on his behalf.

I don't want this disturbing trend to reach the point that I'll have to actually watch an episode of Last Call with Carson Daly.
