• Fatty, Base1, Base2, Thing1, Thing2
• Fatty, Base1, Base2, Thing2, Thing1
• Base2, Base1, Thing1, Thing2, Fatty
• Base2, Base1, Thing2, Thing1, Fatty

• class Base1
• class Base2
• class Thing1
• class Thing2
• class Fatty Base2, private Base1
• public
• Fatty() Base1(), Base2(), two_(), one()
• Thing1 one
• private
