Just do it... better!

Dr. Cheese and the Potato Family
At the grocery store, Mrs. Potato meets her friend Mona, who has lost weight through liposuction. However, some unexpected physical exertion makes Mrs. Potato realize that she is in much better shape than her friend. This is because Mrs. Potato lost weight by eating well and exercising. Her friend did neither, and the liposuction only removed the good subcutaneous fat, not the bad intra-abdominal fat!
