A simple effective model is constructed and solved within Dynamical Mean Field Theory. It is shown to capture all the qualitative and even quantitative aspects of such Griffiths phases.9 pages, 7 figures, one reference corrected; minor corrections includedStrongly Correlated ElectronsDisordered Systems and Neural Networkstext
