Harry tries to make up for his prom night fiasco with Anita by planning a fun afternoon for her in New York City. Harry takes her up to the Rockafeller observation deck to view the skyline, but to their dismay, it is too foggy see anything. Harry asks Janice, a meterologist, to help them figure out when the fog will lift. She explains that fog forms when the temperature drops to the dew point and disappears when it rises above it. Within an hour, the temperature rises above the dew point and Harry and Anita are able to take in the clear, beautiful view.
