A doctor tells a group of patients, "The material we put into our stomachs is terrible. Red meat is awful. Soft drinks corrode your stomach lining. Chinese food is loaded with MSG. High-fat diets can be disastrous, and none of us realizes the long-term harm caused by the germs in our drinking water. But there is one thing that is the most dangerous of all. Can anyone here tell me what food it is that causes the most grief and suffering for years after eating it?" An old man raises his hand and says, "Wedding cake."
