As Burns' loyal lickspittle, Waylon Smithers' duties include squeezing juice for Mr Burns every morning, tucking Mr Burns in at night, moistening Mr Burns' eyeballs, assisting Mr Burns with chewing and swallowing, removing Mr Burns' dead skin, lying to Congress, and some light typing.
His intense devotion to his job is no doubt largely due to his deep feelings for his boss, whose frail, liver-spotted body holds a strange attraction for Smithers.
A stickler for rules, disdainful of his underlings, and generally willing to do Burns' dirty work at the power plant, Smithers nonetheless retains some small shred of morality, occasionally taking a stand against Burns' more diabolical schemes, even at the expense of his job.
Outside of work, Waylon has found an outlet for his more creative side through his Malibu Stacy collection (the world's largest), and by designing screen savers for his computer featuring naked poses of Mr Burns.
