This is hilarious.

Many a visitor to New York's Museum of Modern Art has probably thought, "I could do that."

A British graffiti artist who goes by the name "Banksy" went one step further, by smuggling in his own picture of a soup can and hanging it on a wall. Staff at the New York Met discovered and removed their new aquisition early Sunday morning while Banksy's discount soup can print took pride of place in the MoMA for over three days before being torn down.

The prank was part of a coordinated plan to infiltrate four of New York's top museums on a single day.
Banksy said he conducted all four operations on March 13, helped by accomplices who filmed him and provided distractions where necessary.

"They staged a gay tiff (lovers' quarrel), shouting very loudly and obnoxiously," said the artist, declining to give his real name or any personal details beyond his occupation as a professional painter and decorator.

OK so he's the stereotypical artist against the war and US culture, but these photos of him placing the artwork and his artwork are hysterical.
