King of the Hill

Bill of Sales (4x17)

:

Peggy gets caught up in a pyramid scheme, selling Metalife health bars. When she discovers that Bill has a talent for selling the product, she enlists his help. To keep him working for her, she realizes that she has to be mean to him, because being treated badly is the only thing Bill knows how to respond to. Despite all of the recognition that she gets, it isn't worth belittling a friend.
