“The most ridiculous thing I ever heard was about a Haim Steinbach that had cheese doodles in it. The cheese doodles got maggots, and they were trying to decide whether to inject formaldehyde into the cheese doodles or replace it with new cheese doodles. That seems like an easy question, as long as cheese doodles exist.”
