Driver who works for a crowd-sourced taxi service is accused of stealing celebrity handbags with the help of one of his passengers. Peter and Jared have their work cut out for them when it's revealed the passenger used a fake identity to book the rides, and left their client to take the fall. The guys must find the mystery girl and convince her to confess, but when they do, they discover the driver's crush on her is so debilitating, it's almost clinical, giving them no choice but to put his neurochemicals on the stand and prove his "crush" is akin to that of a "judgment impairing drug." Meanwhile, furious that his caricature has been removed from a local restaurant, Infeld sucker-punches the owner, re-sparking a bitter rivalry. To avoid a costly settlement that could bury him and the firm in debt, Franklin & Bash arrange a more old-school measure to appease the victim: Infeld must take one punch from guest star Mike Tyson.
