The Simpsons is an American animated television sitcom. The Sopranos has been referenced on The Simpsons numerous times.
In the episode "Poppa's Got a Brand New Badge" (2002), the Mafia drive across Springfield to the Simpson family's home with the theme song "Woke Up This Morning" by Alabama 3 playing, parodying the The Sopranos intro.
Later on, in the episode "The Mook, the Chef, the Wife and Her Homer" (2006), when Fat Tony is driving his Lincoln Navigator in the carpool, The Sopranos theme song is heard. The promotional poster for that episode was also a parody of a season 6 promo, and Sopranos actors Joe Pantoliano and Michael Imperioli voice mob characters in this episode.
Additionally, in a 2003 Simpsons comic story, The Sopranos was referenced with a TV show called The D'ohpranos.
