Littlehorn & Associates

Littlehorn and Associates is a firm that collects ears from the Vault Dweller if they have the Contract Killer perk, and is headed by Daniel Littlehorn. If you maintain or achieve a Very Evil level of Karma upon turning in your ear(s) to him you will get a bonus. It is not revealed why he wants ears from "Good People," but mentions something about maintaining a certain balance in the Wastes. Littlehorn and Associates is in direct contrast to the Regulators and is located in a large shed in the Scrapyard.
