| Character Information
John Baldessari is an American conceptual artist.
When working for the Springfield Shopper, Marge went to visit John Baldessari at an art gallery he was hosting. Marge spoke to him about him changing from painting giant mouths to painting giant noses. He told Marge that the mouth had its day and it was time to find out what the nose knows. He then told Marge that pretty much everything he says is horrible.
