Anderson Cooper seems unflappable. The CNN host comes across as a consummate professional, a cool customer who dabbles in heroism (he saves kids!). Last month, Cooper had no trouble dealing with the challenge of covering the aftermath of the Haiti earthquake.

MTV's Jersey Shore stars, on the other hand, get under his skin. During his show Wednesday night, Cooper broke into a scathing indictment of headline-grabbing diva 'Snooki,' sniping at her promiscuity and her looks.

Have you seen her in the hot tub? I've seen that on The Soup. It's not pretty. It's like a Petri dish.

The rant (first picked up by Mediaite) has yet to elicit a response from the Jersey Shore crew. Perhaps Mike "The Situation" Sorrentino will pay Cooper a visit.
