I used to have a little black and white tv in my bedroom when I was in high school. When my alarm went off in the morning I would reach up and turn it on and fall back into bed. The theory was it would help me wake up. I half asleep watched a lot of Magic School Bus. One morning the audio track had been mixed up with the descriptive audio for the blind track. Which was sort of great to listen to, since I had my eyes closed as I fell back asleep. I noticed though, that while they described all of Liz's crazy antics, they never bothered to describe who Liz was.
So you might get a description like:
Liz hops onto Mrs. Frizzle's chair and the two wink at each other.
I'm sure the thing you would picture (having never
seen the show) would not be:
They did, however, describe Mr. Frizzle's outfit when she first walked into the room.
