  I selectively review the various dynamical scenarios that have been explored
to date, especially those that illustrate the conundrums. In short, although
the existence of asymmetries are convincing enough, the interpretation remains
ambiguous. A coherent picture for the Milky Way asymmetries is an obvious lack;
each mechanism is considered independently of all others. With this motivation,
I will present a nonstandard picture which has the potential to explain some of
the signatures and a few of the conundrums. Moreover, it illustrates global
features are dynamically connected and I believe that it is time to revisit the
Milky Way in this context. Finally, I will end with a wish list for future
work---both observational and theoretical---designed to help us pin down the
Milky Way.
