Since the report of the SAMPLE Collaboration suggesting the strange-quark contribution to nucleon magnetic moments, G_M^s(0), may be greater than zero, numerous models have appeared supporting positive values for G_M^s(0). In this paper the bizarre physics associated with G_M^s(0) > 0 is illustrated. Using new lattice QCD results, our best estimate for G_M^s(0) shifts slightly from G_M^s(0) = -0.75 +/- 0.30 mu_N, to G_M^s(0) = -0.62 +/- 0.26 mu_N.
