We exhibit a compact metric on the 2-disk having no upper bound for the Morse index of simple closed geodesics. Consequences: On any surface there is a metric having simple closed geodesics of arbitrarily high Morse index. On any 3-manifold there is a metric having embedded minimal tori of arbitrarily high Morse index. This is joint work with Tobias Colding.
