Actually a well modelled nonlinear system usually has saturation and dissipation,
so it is less likely here (unless it really happens in real life ) than in the "Assume speherical weakly coupled cow" model.
Coupled oscillators are really interesting because couplings that seem "small" as in irrelevant
can produce macroscopic effects. 
Now, if these were mortgage backed securities instead of cows, well, anything is possible.
LOL.
