No, Joe. "D'-O-H" is a three-letter word.

Nightly news shows still haven't tired of replaying Palin's infamous interview with Katie Couric. But how many times have they replayed Biden's botched interview with Couric last month -- in which he cluelessly claimed: "When the stock market crashed, Franklin D. Roosevelt got on the television and didn't just talk about the, you know, the princes of greed. He said, 'Look, here's what happened.'"

Er, here's what really happened: Roosevelt wasn't president when the market crashed in 1929. As for appearing on TV, it was still in its infant stages and wasn't available to the general public until at least 10 years later.

During the lone VP debate earlier this month, the increasingly erratic, super-gaffetastic Biden demonstrated more historical ignorance that Palin would never be allowed to get away with: "Vice President Cheney's been the most dangerous vice president we've had probably in American history," he said. "He has the idea he doesn't realize that Article I of the Constitution defines the role of the vice president of the United States, that's the executive -- he works in the executive branch. He should understand that. Everyone should understand that."

Article 1 of the Constitution defines the role of the legislative branch, not the executive branch. You would think someone who has served 36 years in government -- the same someone who is quick to remind others of his high IQ and longtime Senate Judiciary Committee chairmanship -- would know better.

Biden's erratic and gaffetastic behavior is the least of America's worries. He's worse than a blunderbuss. He's an incurable narcissist with chronic diarrhea of the mouth. He's a phony and a pretender who fashions himself a foreign policy expert, constitutional scholar and worldly wise man. He's a man who can't control his impulses.

And he could be a heartbeat away.

Now, back to your regularly scheduled Palin-says-"You Betcha" skit.
