DeLaWho? DeLaWhat? DeLaWhere?

Casey Knowles of Bonney Lake, Wash., was recently watching Jon Stewart lampoon Hillary Clinton's well-known "3 a.m." ads on "The Daily Show" when her brother noticed something."They were parodying this ad, kind of poking fun at it. They were replaying it. We paused it. My brother was like, 'Is that Casey?' And we just erupted," Knowles said on "Good Morning America Weekend Edition" today. "Sure enough, it's me."

An image of an eight-year-old Knowles appears in the ad, shown sleeping soundly in bed. The Clinton campaign legally purchased the file footage of Knowles from Getty Images.

Clinton's ad aimed to emphasize her experience and say she'd be a strong national security candidate. The ad was a play on a 1980s-era advertisement with a similar theme: if there was a middle-of-the-night national security emergency, who would you want to have answer the phone and deal with it?

Ironically, though, the now-17-year-old Knowles would want Clinton rival Barack Obama to answer any important 3 a.m. calls coming into the White House.

Knowles' image originally was shot for a railroad company advertisement, but the teen said she harbors no resentment toward the Clinton campaign for using her image.
