"Funny Money" is both the title and the main subject of this episode, as Riggs and Murtaugh (Clayne Crawford, Damon Wayans Sr.) try to track down counterfeiters. Several teens become caught up the illegal scheme. Murtaugh tries to resolve issues he's having with son RJ (Dante Brown), while Riggs revisits a part of his past. Kristen Gutoskie and Rex Linn continue their guest roles. Ernie Hudson ("Ghostbusters") also guest stars.
