1. Because

Scene 1. Ted and Sally on a porch overlooking the water in Nice or some other resort. The scene is all yellow and green.

Scene 2. City, street scene. All purple.

SUBTITLES: So they moved. In the place where they moved, everything was purple. And they were happy.

Scene 3. Yellow scene. A nursery. Everyone is happy. There are children. Smoking orange and blue SUBTITLE comes on and says “END.”
