Rick Perry Gaffe in Debate Video?

Rick Perry was the victim of one of the worst gaffes in any political debate yesterday.
I watched the debate live yesterday and I want to see the video on Youtube, so I can see what people think of Rick Perry's gaffe.
I was surprised by his lack of knowledge of our own government, specially when he is running for the presidency of the United States. At the very end of his gaffe, Rick Perry said 'oops' and made the whole thing worst.
Ron Paul was next to him during the debate and he didn't help him, it was so awkward and uncomfortable to watch. Please point me to the Youtube video of Rick Perry's gaffe.

Rick Perry said that one gaffe in a debate may in fact humanize him and certainly will not tank his campaign.
Governor Rick Perry of Texas said his brain freeze shows that he is not the slickest politician among the Republican candidates. I posted the video of the gaffe below.
Rick Perry went blank while announcing the three federal agencies he would target to tame the budget deficit.
Here's the youtube video of the debate, not the whole thing, just Rick Perry's gaffe.
