ANIMATION: The evolution of home heating.moreless
The animation which follows Sarah Jessica Parker's Annie segment displays a thermometer reading both Fahrenheit and Celsius scales. The numbers on the Celsius scale are not listed properly, going from 10° to 0° to -10°, then 0° again, then another -10° before the last figure, -40°, gets it back on track.
(Read the tease and you can tell this show is meant strictly for the Northern Hemisphere.) LISA (sighs): Boy, I'm tired of winter. TRINI: Me too. We've all had colds. MARC: We can't play outdoor sports. TRINI: Every time we want to go out, we have to get all wrapped up. Where's the sun? MARC: It's weinter. It's farther away. LISA: No, it's nearer. MARC: What? LISA: It's nearer to us in the winter than in the summer. MARC: Well, that doesn't make any sense, Lisa. If it were nearer, it would be hotter. LISA: I can't explain it. I just know that the sun is nearer to the Earth in the winter than in the summer. I read it somewhere. MARC: Prove it LISA: How. TRINI: Well, we could bring the sun in here and ask it. MARC: I don't think that's too practical, Trini.
