My perfect Scrooge would mix the Burgermeister Meister Burger, Danny Devito and Billy Bob Thornton in a blender...
I see Scrooge as foul on the outside as he is inside. He'd let his clothes rot before spending money on buying new ones. He washed once a month saving money on water.
I imagine a post Christmas Scrooge that didn't change his frugal personal hygiene habits. He now uses the saved money on others.
Years later, Scrooge invented the "derby" hat when he wanted a cheaper "top" hat that used less money for material.
