There's a monlogue in the play "Where Has Tommy Flowers Gone" by Terrence McNally. It's about a high school kid who is telling about his experience being called into the principal's office.
More popular, but maybe overdone, are the monologues from Neil Simon. Either "Brighton Beach Memoirs" or "Biloxi Blues"
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
