 Obsessed fan Marci Maven, played by Sarah Silverman (qv),  complains throughout the episode about her favorite TV shows new  theme song. This is a reference to the minor controversy that brewed  among Monk fans over the introduction of the new theme song "Its A  Jungle Out There" written and performed by Randy Newman (I) (qv)  in the second season of Monk. Many fans have clamored for the return  of the original theme song by Jeff Beal (qv), even going so far as  to organize letter writing campaigns and petitions to USA Network  demanding its return. At the end of the episode Marci Maven asks  Adrian Monk to promise that if he ever gets his own show, he wont  ever change the theme song. When Monk agrees to the promise, the  original theme song by Jeff Beal begins to play as the scene fades  to credits.
