The panelists also engaged in a competition for the Golden Ear in this season.

Guest panelists included Joel McHale in the third and fourth episodes, season two winner Wayne Brady in the sixth episode, Niecy Nash in the seventh episode, Cheryl Hines in the eighth episode, Jay Pharoah in the ninth episode, and Craig Robinson in the tenth episode.
