The Netherlands...Is that like "The Donald"?

This is the country that always confuses me. The call themselves the Netherlands, but they are also Holland. What are the people referred to as? (Please spare me the requisite nasty answers from the Belgians out there.) The Dutch.

Muliple Personality Disorder, thy name is Holland. (or Van Multiple Personality Disorder)

Also, why "The Netherlands"? I always think of "nether regions". Is Holland the crotch of Europe?
