Over the past two years, deep searches with the GBT have uncovered over 50 new binary and/or millisecond pulsars in six globular clusters. The biggest surprise was 30 new pulsars in the rich cluster Terzan 5 alone. Follow-up observations have shown that many of these new systems are truly unique and/or exotic objects that could only have been produced in dense cluster cores after stellar interactions. Some of the stranger members of the new zoo include the fastest known spinning neutron star (PSR J1748-2446ad at 716 Hz), 9 highly eccentric binary systems, at least 5 eclipsing systems, and 2 millisecond pulsars which seemingly have main-sequence-like stellar companions. Several of these pulsars are already constraining the equation of state of matter at supra-nuclear densities, while others will provide masses of spun-up neutron stars and interesting tests of gravitational theories in the years to come. In addition, the pulsars will allow us to probe a wide variety of other astrophysics such as eclipse mechanisms, cluster dynamics, and the structure of the interstellar medium.
