Mrs. Photic: "OH MY GOD! DID THE LIGHTS JUST FLICKER?!!!"
Dr. Grumpy: "Uh, I think so, when I turned them on. They're fluorescent."
Mrs. Photic: "THIS MEANS SOMETHING!"
Dr. Grumpy: "Everything is fine, ma'am. It only means they're on. Have a seat over there, and let me take your blood pressure.."
Mrs. Photic: "They're not going to flicker again, are they?"
Dr. Grumpy: "I don't think so, but they're old fixtures."
Mrs. Photic: "If they do, I'm leaving. For all I know you're one of them."
