Piet Mondrian “Composition in Red, White, and Blue” / vomit

(In 1996, a twenty-two year old art student named Jubal Brown ate blue cake icing and blue Jell-O prior to entering the MoMA. Once inside, he proceeded to make himself projectile vomit onto the work, staining the work blue. “I found its lifelessness threatening and it made me sick,” he later said. Damages were able to be repaired.)
