Which scene from the play best exemplify the theme that absolute power corrupts

The scenes where Faustus plays practical jokes on people to exemplify the theme that absolute power corrupts the best of people. Faustus works magic to make horns appear on the knight's head and sells an enchanted horse to a horse-courser. He even upsets the pope's banquet. Faustus could have used his power for greater causes, but he squanders them on lowly pursuits. He loses sight of his ambitions once he tastes power.
