Waylon Joseph Smithers, Jr. (better known as "Mr. Smithers" or simply "Smithers") is Mr. Burns's personal assistant, executive, and self-proclaimed best friend on The Simpsons. He has lived with Burns since he was an infant, and though partly raised by him, Burns has never seen Smithers as a stepson, an heir, or generally anything worth his genuine warmth or care; nonetheless, his loyalty to his evil boss is sincere.
