Unfire

J. J. Jameson: [talking to Peter Parker] Where you been? Looked for you all morning! Why don't you pay your phone bill? Mad scientist goes berserk and we don't have pictures! […] Where were you? Photographing squirrels? You're fired! Receptionist: Chief, the planetarium party. J. J. Jameson: Oh, right. You're unfired. I need you to come here. What do you know about high society? […] Don't answer that. My society photographer got hit in the head by a polo ball. You're all I got.
