Observations of extrasolar planetary systems have uncovered classes of giant planets that - by virtue of their short orbital periods, high eccentricity, or resonant orbits - have no analog in our Solar System. I will discuss the extent to which these unusual properties can be understood, either as a consequence of interactions between forming planets and the protoplanetary disk, or via the chaotic evolution of multiple planet systems. The planetary observations, when combined with surveys of nearby star formation regions, also provide circumstantial evidence that massive planets may form more rapidly than previously thought. I will compare different theoretical models for how rapid planet formation might occur, via gravitational disk instability or modified versions of core accretion.
