DX lens on FX sensor DSLR

This may sound like a dumb question, but is there a crop factor when using a DX lens such as 18-55mm AF-S 3.5-5.6G on a full frame sensor camera?
For some reason, this DX/FX question exercises the pedants. Obviously, DX lenses aren't going to cover the larger sensor properly, so you would have to crop the image to get a decent result. - However some FX cameras can be set to automatically crop the sensor when a DX lens is mounted.
Perhaps that it what you meant?
On the other hand, FX lenses on a DX sensor give happiness.
I bypass the spurious crop factor talk when explaining the effect of sensor size: "A small sensor only requires a miniature lens for the same result". Quality may be less.
