A doctor was addressing a large audience:

 

"What we put into our stomachs is enough to have killed most of us sitting here years ago. Too much red meat is unhealthy. Soft drinks corrode the stomach lining.  Chinese food is loaded with MSG. High fat diets can be disastrous, and none of us realize 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?"

 

After several seconds of quiet, a 75-year-old man in the front row raised his hand, and softly said, "Wedding Cake."
