"Mr. Burns, I'm afraid you are the sickest man in the United States. You have everything." Mr Burns is old. I mean seriously old. How many people do you know own a driving licence that expired in 1909? In this episode from season 11, Mr Burns visits a doctor for a check up. The results are naturally hilarious. It turns out that the oldest man in Springfield is also the sickest man in the United States, suffering everything from juvenile diabetes and a hysterical pregnancy to a 'cute little cuddle bug known as pancreatic cancer'. Mr Burns has only survived as long as he has because all of his afflictions are in perfect balance, like the Three Stooges all trying to squeeze through a door at once. Most would be horrified to receive such news but with child like naivety, Burns convinces himself that this condition has made him indestructible, despite being warned that even the slightest breeze could be fatal.
