Planet (Gangster's Paradise)
From Tardis Wiki, the free Doctor Who reference
The Tenth Doctor and Rose Tyler once visited the Sunset Strip, a market town on what Rose described as "a planet of gangsters". It was a lawless place between galaxies where gangs ran the city and free trade rules applied. Here, the Doctor and Rose became involved in a struggle between Don Corpulone and Doll Corpulone over possession of a glitterbird egg. (COMIC: Gangster's Paradise)
