Huey and Riley try to convince Grandad that his new girlfriend Cristal (like the champagne) is actually a prostitute. Of course, Grandad doesn't believe them, even when she spends all his money. But when A Pimp Named Slickback shows up, the truth is revealed.

District Attorney and law-abiding citizen Tom Dubois fits the description of the elusive "X-Box Killer" and is arrested. Huey has to find the real killer before Tom is shipped off to "real" prison where he will most assuredly become "someone's girlfriend."
