Banksy was also credited with the opening couch gag for the 2010 The Simpsons episode "MoneyBart", depicting people working in deplorable conditions and using endangered or mythical animals to make both the episodes cel-by-cel and the merchandise connected with the program. His name appears several times throughout the episode's opening sequence, spray-painted on assorted walls and signs. Fox sanitised parts of the opening "for taste" and to make it less grim. In January 2011, Banksy published the original storyboard on its website. According to Banksy, the storyboard "led to delays, disputes over broadcast standards and a threatened walk out by the animation department." Executive director Al Jean jokingly said, "This is what you get when you outsource."

He had discovered Banksy on a chance photo shoot in Bristol in 2001 while working as picture editor of Sleaze Nation magazine, and brought him to public attention along with a roster of other urban artists... Lazarides and Banksy parted company in 2009, a mysterious split about which both parties have remained tight-lipped.
“Banksy is unique to the art world. No other artist captures the hearts and minds of the public like he does,” Syer said. “What this person today seems to have done is needlessly ruin a print worth around £40,000 and reduce its value to almost nothing…[there] are limited numbers of Girl With Balloon prints in the world, today, we lost one and it's a crying shame.”
Among the structures photographed prior to the opening were a large pinwheel by Banksy, Horse Scaffolding Sculpture by Ben Long, and a twisted truck sculpture, Big Rig Jig by artist Mike Ross which was previously shown at Burning Man in 2007. Works by 58 artists, including Jenny Holzer, Damien Hirst, Jeff Gillette, Jimmy Cauty and Bill Barminski were featured in the park. Banksy said he contacted the "best artists I could imagine" to exhibit, with two artists turning him down.
