When talking to another developer today we came across a question that we can't find the answer to so I was hoping someone here knew the answer.  I know that you can create a visualforce page with more than one extension.  My questions are:

1. Why would you use more than one?

2. If you have more that one in what order does visualforce look for your method?

3. What happens if you have a method with the same name on different extensions?
