In the time since its launch, the \textit{Fermi Gamma-Ray Space Telescope} has provided new and unparalleled views of the $\gamma$-ray sky, dramatically increasing our understanding of sources of high-energy radiation. During that same time, however, its ``unassociated'' sources have provided a consistent mystery: approximately one third of the modern gamma-ray sky remains completely unaccounted for in other electromagnetic regimes. While some of the fainter sources simply pose challenges in achieving the necessary signal-to-noise ratio, others are well constrained and have resisted traditional investigations for years, and in some cases, for over a decade. Radio astronomy has traditionally been the best complement to gamma-ray astronomy, given its particular leverage over Active Galactic Nuclei and pulsars, two of the primary sources in the $\gamma$-ray sky. Using this leverage, we aim to illustrate continuations of successful approaches, introduce novel approaches capable of unveiling sources that have so far evaded detection, and highlight one of the more aesthetically captivating instances of success from these fields: the Cannonball Pulsar J0002+6216.
