British graffiti artist Banksy was apparently given free reign over the opening credits and "couch gag" of "The Simpsons" tonight, and boy did he go to town. The typical journey through Springfield in the opening seconds is definitely a little off — a bird clutching the artist's famous rat flies across the screen, a "Banksy" tag is on the Krusty billboard, and Bart has written "I Must Not Write All Over the Walls" not just all over the classroom blackboard but the walls themselves. None of that prepares us, though, for where Banksy takes us with the "couch gag." We're suddenly in Asia, where child slaves ink every frame of a "Simpsons" episode (in fact, most of this work is done in Korea), and then we go down into a dungeon where "Simpsons" merchandise is made. Down there, live cats are turned into the stuffing of Bart toys, a wheelbarrow filled of which is carted by a slave panda; the tongue of a decapitated dolphin's head licks close a box with more merch; and a chained-up unicorn's horn is used to pop out the center of "Simpsons" DVDs. And all of this under the hulking 20th Century Fox building, which apparently approved it. The opening is an absolute must watch. It's after the jump.
