"Counting up sleepers..? Just how we do it..? Really quite simple, There's nothing much to it"
The Audio-Telly-o-Tally-o Count chap from Dr. Seuss's Sleep Book is a person who work the night shift operating a Machine that is known as the Audio-Telly-o-Tally-o Count.
The Machine he operates is in a Plexiglass dome that is located on a mountain between Reno and Rome. The Audio-Telly-o-Tally-o Count Machine is able to look into anyone's home and listen to who on earth may be asleep. Once a person flops into bed falling asleep, the Audio-Telly-o-Tally-o Count machine jiggles and a few white biggle balls drop down into a cup with a pipe attached to it.
The Chap operating the Audio-Telly-o-Tally-o Count machine takes note counting the amount of balls that drop and as the big role of paper rolls down, the screen below sums of the total amount of sleepers sleeping at night. Attached to the Audio-Telly-o-Tally-o Count is a piano below which probably plays soft lullaby music for the sleepers to listen and sleep to.
