  The quantum mechanical behavior of a particle in a double well defies our
intuition based on classical reasoning. Not surprisingly, an asymmetry in the
double well will restore results more consistent with the classical picture.
What is surprising, however, is how a very small asymmetry can lead to
essentially classical behavior. In this paper we use the simplest version of a
double well potential to demonstrate these statements. We also show how this
system accurately maps onto a two-state system, which we refer to as a `toy
model'.
