Synopsis by Hal Erickson
In the first episode of a two-part story, police officer Joe Luria (Scott Michael Campbell) begins laughing uncontrollably as he chases after a perpetrator--and continues to laugh even after he himself is shot! Though the gunshot won't kill him, Joe's acute euphoria may indeed prove fatal . . .especially after he goes blind. But House(Hugh Laurie) is less concerned with Joe than with his own colleague Foreman (Omar Epps), who suddenly begins exhibiting the same bizarre symptoms--just before Joe lapses into terminal unconsciousness!
