Kerouac Pie Calculation

"... apple pie and ice cream in a roadside stand... I ate another apple pie and ice cream... I knew it was nutritious and it was delicious, of course... I ate apple pie and ice cream - it was getting better as I got deeper into Iowa, the pie bigger, the ice cream richer... she made the sweetest cherry pie in Nebraska, and I had some with a mountainous scoop of ice cream on top." In Chapter 3 of ON THE ROAD, there is a serving of pie and ice cream every 2 1/2 pages!
