Ashley Lendzion, Riki Lindholme, and Heather Morris have put together a fitting Glee tribute with "Nuthin' But A Glee Thing": the girls cover a popular song that is completely incompatible with their musical sensibilities, recruit a random guest star (Modern Family's Sofia Vergara!), and Heather Morris is by far the best part.

The clip has plenty to offer.  Linkdholme has long been musically funny as the taller, blonder, Garfunkler half of Garfunkel & Oates.  Morris has surprisingly mad game on the mic.  And more than a few Glee cast members -- including Matthew Morrison, Cory Monteith, Harry Shrum, and Naya Rivera -- stop by for goofy cameos.  If you're a fan of Glee or girls performing gangster rap, hit the jump to watch.
