Gov. Tim Pawlenty appeared on ABC's This Week with George Stephanopoulos and was thrown for a loop when asked how many tax returns Romney demanded of him during the vice presidential vetting process:

You can see him taking a deep breath before he says, "I don't know the exact number..."

A dubious declaration. You really don't remember if they asked to go back to 2008, 2005? Less? More? The year wouldn't stick out in your mind?

Pawlenty had obviously been well-prepped for this media appearance, dutifully spouting all the appropriate Romney propaganda and lies.

But, and you must watch the video to get the full affect, it's obvious he was totally unprepared to answer this obvious question. He stammers and fumbles it, it's really a thing of great beauty to watch Pawlenty struggle.

He eventually settles on an appropriate, no comment "we don't get into the details of the vetting process..."

Of course, not before revealing that Romney demanded more tax returns from Pawlenty than Romney believes the American voters are due.
