Does anyone know the origin of this line?

Does anyone know from which script(play or movie)the
following lines were extracted? I was watching the movie "Fame" and one of the students were reading it in the audition.

You swine, you coward, you cad!
You dare judge me in my misfortitude!
You dare to ask me the question who is the father
of my child? You! You! I point to you, Nigel!

Thank you in advance.

Sorry for posting the same question twice. I thought I mis-posted my first question.So
please delete my first one.
