Chinese Moon Probe Flies By Asteroid Toutatis

With Weak Stability Boundary theory trajectories you can basically get from a lunar transfer orbit (or either ES or EM L1/2) to anywhere else around without spending any fuel, if you are willing to wait long enough. This pdf presentation [utexas.edu] should give you the idea.

Now, in practice you can't do it with no fuel, but if you are willing to be patient, you can do amazing things with a piddling expenditure of delta-V.
