Abstract　 　　 

　The Large Area Telescope (LAT) on board the Fermi satellite provided us an excellent opportunity to study gammaray pulsars with over 140 detections after five years of operations. In the first part of this talk, I present 7 new gammaray pulsars with an eclectic mix of properties. They illustrate the biases existing in the current gammaray pulsar sample and mark the transition from the early part (bright pulsars) to the later part (faint pulsars) of the Fermi mission. The second part concerns possible constraints on neutron star moments of inertia by studying a sample of high gammaray efficiency pulsars in the Second Fermi-LAT pulsar catalog.
