makes Bart scream in terror. Bart Simpson's Dracula Before this segment begins, Bart says that the story was supposed to be based on the 1903 painting A Friend in Need from the Dogs Playing Poker series by Cassius Marcellus Coolidge, but it was "far too intense" (Homer has a psychotic episode upon seeing the painting), so they "just threw something together with vampires." In a parody of Bram Stoker's Dracula, after a news story about several vampire attacks (attributed by the police to a mummy), Lisa begins to suspect that Mr. Burns is a vampire when he is seen on the same report with a drop of blood below his mouth, but the rest of the family dismisses her concerns. The family is invited to Burns' castle in Pennsylvania for a midnight feast, where Bart and Lisa discover a secret staircase descending to an eerie basement filled with coffins. As they investigate, vampires emerge from the coffins and encircle them while Lisa reads through Burns' autobiography "Yes, I Am a Vampire" (with a foreword by Steve Allen). Lisa escapes, but Bart activates the "Super Fun Happy Slide", causing him to slide back down into the vampire pit, whereupon he is captured and bitten by Burns. Lisa tries to warn her parents, but Burns reappears with Bart who is now very pale and is behaving oddly. But these factors get little attention by the family. Later that night, Lisa is awakened by a now undead Bart and his vampire friends outside the bedroom window, in an homage to Salem's Lot. When Bart is about to bite Lisa, Homer and Marge interrupt and discover that Bart is a vampire. Lisa claims that the only way to restore him is to kill the head vampire, Burns. The family returns to Burns' mansion, where Homer drives a stake through Burns' heart (after first hitting his crotch), causing him to dissolve into sand (but he briefly comes back to life to tell Homer "You're fired!"). The next morning, however, Lisa discovers that everyone else in the Simpson family is a vampire, with Marge as their head. The family closes in on Lisa, but instead of attacking, they break character and wish the home audience a happy Halloween. Then, they all harmonize "Hark the Herald Angels Sing", parodying A Charlie Brown Christmas. Production "Treehouse of Horror IV" was directed by David Silverman and co-written by Conan
