Mr. Burns' extreme old age is a frequent source of humor on the show, he is occasionally referred to as "Springfield's oldest resident" but his exact age is uncertain. In "Simpson and Delilah" he said he was 81 years of age, while in "The Mansion Family", he said he was over 100 years old. In several episodes, including "Who Shot Mr. Burns? (Part One)", "Homer the Smithers", and "A Hunka Hunka Burns in Love" his age is specifically stated to be 104.
