Treehouse of Horror X
Oops sorry you can see this? You need flash
An x-ray machine scanning Halloween candy malfunctions gives Bart the ability to stretch his body like rubber and Lisa super strength. They become a superhero duo, calling themselves "Stretch Dude & Clobber Girl". Later, Lucy Lawless (dressed as Xena) addresses fans at a science fiction convention. Comic Book Guy, who has styled himself as a villain called "The Collector", kidnaps her using a magnet to attract her metal breast plate. Lawless tries to remove the breastplate but stops after she notices that the fans would take pictures of her topless. The Collector takes her to his lair, where he puts her in an aluminized PET film bag for "safekeeping" and imprisons her in a room of other similarly-captured celebrities. Stretch Dude and Clobber Girl then enter the fray in an attempt to free Xena, but they are soon captured as well. The Collector suspends the duo over a vat of Lucite. After feigning interest in the villain, Lawless starts clobbering him. The Collector grabs his limited edition double edged lightsaber from Star Wars Episode I: The Phantom Menace and ignites the blades, but when Lawless reminds him that he has removed it from its original packaging, he panics and ends up falling into the Lucite. Lawless then flies the children home.
