A telephone number used in the song "Skandal im Sperrbezirk" by the spider murphy gang.
The lyrics display the number as the one used by a whore called "Rosi" and a few weeks after the song was released in 1981 an old lady recieved a number of weird calls, as the band did not check wether or not the number was taken.

Large, beautiful breasts that are keep well consealed and initially appear to be much smaller and less impressive than they actually are until unleashed.
