Normally, the National Gallery of Art is a serene place, where art lovers view priceless masterworks and tourists plop down during the sweltering summer to just sit enjoy the air conditioning. But someone going nuts, pounding and attempting to pull a painting from the wall, then being “immediately restrained and detained” by “a guy who was visiting the gallery,” well, that’s a rare occurrence. But that’s what happened on Friday, when an unidentified woman became overly perturbed by Paul Gauguin’s “Two Tahitian Women,” which is currently on display as part of a long-term exhibit at the Gallery:

Screaming “This is evil,” a woman tried to pull Gauguin’s “Two Tahitian Women” from a gallery wall Friday and banged on the picture’s clear plastic covering, said Pamela Degotardi of New York, who was there.

“She was really pounding it with her fists,” Degotardi said. “It was like this weird surreal scene that one doesn’t expect at the National Gallery.”

Hey, who knows? Maybe she was just a really jealous Cézanne fan.
