During a conference about Art in the Culture of Fear - on the day advocate of dietary reform John Harvey Kellogg died - I divided the audience in two groups. Inbetween I 'sowed' cornflakes. Then I proceeded to grab and chew the cornflakes in my mouth. Not swallowing the paste I used it to build a wall between the two audience groups. As my mouth started bleeding from chewing the hard cornflakes everybody in the audience left.
