In a new campaign ad running in Iowa, Rick Perry seeks to capitalize on the anti-momentum he got when he struggled to remember which federal agency he'd cut in a televised debate.

I'm Rick Perry and I approve this message. 

Haha, good one Rick Perry. Remember, we're laughing with you at that last joke. With you ... Perry, who's already joked about his "Oops" moment with David Letterman, will be on Jay Leno tonight, Politico reports, and will run the ad before and after his appearance in Iowa's media markets.
