[O]ne day, in a weak and hungry moment, my roommate and I succumbed to a bit of larceny. A greengrocer's truck had parked down the street and was left unattended. We grabbed the first crate we could off the back. It turned out to be celery. For two days we ate nothing but celery and used up more calories chewing than we realized in energy. "Damn it," I said to my roommate, "What're we going to do? We can't starve." "That's funny," he replied. "I thought we could." [Chuck Jones, "Chuck Amuck," 1989]
