Motivated by naturalness arguments, I present simple supersymmetric models where the lightest Higgs boson cascade decays to 4 light jets, $h \to 2A \to 4j$, through a light pseudo-scalar $A$. This buried'' Higgs boson can be lighter than 100 GeV without conflict with experiments. Utilizing jet substructure techniques, we find that for buried Higgses in the 100-200 GeV range, a 5-sigma discovery can be expected with 25 fb$^{-1}$. \\ \\ \\ \centerline{(Attention: unusual day and room)}
