House (Hugh Laurie) doesn't have too many idols, but 71-year-old cancer researcher Ezra Powell (Joel Grey) can qualify as one of them. After collapsing in his lab, Powell is rushed to the clinic,, where the staff can't agree whether he is suffering from a heart ailment or lung disease. Frankly, Powell could care less: He simply wants to die--and demands that the staff assist him in his demise. Much to the horrified astonishment of his colleagues, House tells Powell that he'll do anything he asks! And in another development, a congestion patient's 17-year-old daughter (Leighton Meester) develops a crush on House and refuses to leave him alone...on or off the job. This episode was directed by ER regular Laura Innes. ~ Hal Erickson, Rovi
