Behind the scenes of Hilton's mock ad

Behind the scenes of Hilton's mock ad: "Paris Hilton didn't need cue cards for her presidential campaign ad.
The 24-year-old heiress memorized her entire monologue, which included Hilton outlining her energy plan, in an online video spoof posted on Funny or Die, the comedy Web site's content director said.

Co-founder Adam McKay came up with the concept for a mock ad starring Hilton, which has received over 3 million views since it was posted Tuesday.

'Adam thought it would be really funny to get Paris to respond to the John McCain ad that featured her,' Funny or Die content director Amy Rhodes told The Associated Press on Wednesday. 'Adam contacted Paris directly, and she agreed to do it. He wrote the sketch. And she really, really loved it.'"
