Do we really need stubs?

Hi there!
If it's possible to change mock behaviour in Rhino Mocks using mock.Stub().Return(), why do we need Stubs anyway?
What do we lose by always using MockRepository.GenerateMock()?
One big benefit of using Mocks instead of Stubs is that we will be able to reuse the same instance among all the tests keeping them cleaner and straightforward.
The moq framework works in a similar way... we don't have different objects for mocks and stubs.
tks in advance!

Exactly my current question (!)
Apparently there's a semantic difference, in that «you should use a mock when you are going to verify that something happened on the object, like a method was called. You should use a stub when you just want the object to be involved in the test to return a value but it is not the thing you are testing» (http://stackoverflow.com/questions/2536551/rhino-mocks-difference-between-generatestubt-generatemockt)
And also «only mocks insist upon behavior verification» (http://stackoverflow.com/questions/1288168/when-to-use-stubs-and-mocks)
I can understand it but couldn't yet "grok" it, in the sense that in practice I feel Mocks go beyond Stubs in functionality. *sigh*
