For reasons nobody can entirely explain, a provocatively dressed Playboy Playmate sashayed across the stage at last night's Mexican presidential debate, causing candidates to ogle openly and igniting some sort of nationwide sex riot, the AP reports.

Julia Orayen has posed nude for Playboy and barely dressed elsewhere, but she made her mark on Mexican minds Sunday night by carrying an urn filled with bits of paper determining the order that candidates would speak. [...] She wore a tight, white dress with a wide, tear-drop cutout that revealed her ample decolletage. The image was splashed across newspaper front pages and websites by Monday.

Orayen's butt derailed the debate entirely. Explained presidential underdog Gabriel Quadri, seen here staring at the lingerie model's ass:

It is impossible not to concentrate your attention on a woman so spectacular.
