FarmVille: CityVille Sam asks "Won't you be my neighbor?"share"

In an attempt to get FarmVille players to try out their new city-building game CityVille, Zynga has released a two-part cross-promotion in FarmVille, adding a new "neighbor" to players' friends bars at the bottom of the gameplay area, in addition to adding a large billboard to one side of users' farms.

If you attempt to "visit" Sam by clicking on her picture in the neighbor bar, as though she were any other friend, you won't be taken to a new farm; instead, you're shown a large ad asking you if you'd like to check out CityVille. If you agree, CityVille simply loads in a new window. If you decline, the window will disappear and you can go back to farming as usual.
