The duck is so egotistical conceited about his hair and his orange tan. Why doesn' he care at all about his morbid obesity?

Does he think people stop at his head and never look down at the big belly that he tries to hide with a suit coat?

You see his belly in all its glory when he plays golf. Coatless then we see his obsesity. Now when he looks in the mirror naked what does he see? A thing of beauty?
