Fame
If you work real hard and fix hundreds, no thousands of faces, maybe you’ll get a plaque or a bronzed statue of a hairlip to hang on your mantel. Maybe the local Kiwanis club will hold a banquet in your honor and they’ll have all-you-can-eat shrimp.
Or perhaps they’ll create a reality show around you following you from country to country, fixing smiles as you go.
At the very least the producers of Grey’s Anatomy might right a walk on part for you if Shondra gets ahold of how saintly you are.
