e excerpt from a speech by the class president petitioning the principal to build a new stadium.

Our stadium is crumbling, and the effects have been felt for generations! If we built a new stadium, our community would benefit, and millions would flock to town for the home games. Profits would soar, as local businesses would be flooded with new clients on game nights. And your legacy as the best principal ever would be established for all to see.
