Synopsis by Hal Erickson
In the conclusion of a two-part story, Foreman (Omar Epps) has begun suffering the same symptoms as wounded police officer Joe Lauria (Scott Michael Campbell), who after being seized by uncontrollable laughter suddenly went blind. . .and just as suddenly died. As Foreman's condition worsens, a desperate House (Hugh Laurie) must rely upon his pet rat to find the source of Joe's fatal euphoria by rummaging through the dead cop's filthy apartment. In the midst of this crisis, Foreman's father Rodney (guest star Charles S. Dutton) shows up to be with his son in his final moments--leading to a bitter quarrel over religious values, even as Foreman is on the brink of death!
