RE: Paul Shaffer and Richard Simmons are fighting to the death. Who wins?

Oh give me a break. Is this not the best scenario to ponder? But I must pose this question: what is the source of their conflict, a conflict that will lead inevitably to the demise of one member of this duo, with the possibility of glancing wounds to the survivor leading to their own demise, or perhaps incapacitation, or at the very least temporary discomfort? It seems likely that the level of motivation for each party might vary, depending on the nature of their dispute. Might we receive some clarification on this point, a point onto which one or possibly two lives might well hang in the balance?
