The Simpsons: 10 Best Ever Treehouse Of Horror Stories
6. Bart Simpsons Dracula (Treehouse of Horror IV)
Theres some absolutely prime C. Montgomery Burns moments in this one - given his extreme age, his grim determination to cling to life by his fingernails, and his fundamentally evil nature, having him play a vampire is the logical conclusion.
On top of that, the ending of the whole episode, wherein the family stand together in the kitchen and sing Hark! The Herald Angels Sing as snow falls indoors is a sharp parody of both the homespun folksiness which characterises a lot of seasonal specials, as well as being a pretty early example of how meta The Simpsons can be - its a take-off of both A Charlie Brown Christmas and how Simpsons Roasting On An Open Fire, the very first Simpsons episode proper, ended.
Its a kind of intellectual leg-stretching exercise, a testing of boundaries before things went really, really meta with episodes like The Itchy & Scratchy & Poochie Show.
