The eigenfunctions e^{i \lambda x} of the Laplacian on a flat torus have
uniformly bounded L^p norms. In this article, we prove that for every other
quantum integrable Laplacian, the L^p norms of the joint eigenfunctions must
blow up at a rate \gg \lambda^{p-2/4p - \epsilon} for every \epsilon >0 as
\lambda \to \infty.
