Janette Barber, Rosie O’Donnell’s chief writer, was escorted out of the ABC building after she was caught drawing mustaches on pictures of Elisabeth Hasselbeck.

The Post’s Adam Buckman reports ABC confirmed in a statement only that “photographs at ‘The View’s’ offices were defaced. Rosie O’Donnell was not in the building. ABC Legal and Human Resources are investigating the matter.” Barber is an old friend of O’Donnell who worked with her years ago on “The Rosie O’Donnell Show.”

Janette Barber would make a great super-villain. While Janette’s peers are out there searching for a superhero’s one weakness, she’ll leave a flaming bag of poop on the doorstep of her arch-nemesis, ring the door bell and run. Then when Batman or somebody comes to stomp it out, their shoes will smell like poop. Next time he saves a hot chick, she’ll think he has really bad b.o. and won’t even give him a hand job. Evil.
