Joe feels some satifaction after finding out that the man who crippled him (it actually wasn't the Grinch who knocked him off a roof) is finally imprisoned. However, when he finds out that man, Bobby Briggs, has escaped, he starts feeling miserable and wants to bring him to justice. Peter volunteers, along with Quagmire, to go hunt Briggs down and bring him to justice. They trace his last known location to a strip club in Atlantic City, where a stripper reveals the address he's currently hiding out at.
The gang goes and finds him, but lose him after a rooftop chase. Thanks to a paper with a Juarez area code on it, they figure out that Briggs is planning to drive out of the country, and the only way on road to Juarez is through El Paso. So the group flies there to cut him off. When he finally reaches the border, Joe chases him down, and after a fight, he decides to get his retribution by shooting him in the kneecaps like Briggs did to him. However, this kills him – but they kick the body into a river flowing in to Mexico and leave. Joe finally has his peace knowing that the man who crippled him is no longer out terrorizing others.
