In another scene in the episode, Homer shows his family an advertisement for his security company. In it, a monster is seen breaking into an elderly woman's house. When the woman screams, the screen freezes and Homer is composited to the screen, instructing the audience about SpringShield's telephone number. In order to composite Homer into the screen, director Michels made use of a greenscreen. The advertisement resumes and the monster is subdued by Homer, Lenny and Carl. Confused, the monster turns to Homer and asks, "friend?" to which Homer replies "the only friend you need is SpringShield," and holds a business card in front of the camera. The monster then puts the card in his wallet and says "monster put in wallet." The monster's last line was written during one of the episode's rewrites, but none of the writers on "The Simpsons"' writing staff has taken credit for it. The line has since become very popular with the series' writing staff; Jean said that it was "very funny and unusual for a television show," and Gould considers it to be his favourite joke in any episode he has ever written. At the end of the episode, Maggie saves Homer by shooting Fat Tony's gang members with a rifle, as a reference to the two-part episode Who Shot Mr. Burns? from seasons 6 and 7, in which it is ultimately revealed that Maggie shot Burns after his gun fell into her hands. The scene was conceived by series co-creator and executive producer James L. Brooks while writing notes during the episode's first table-read.
