Whenever you quote a play in your essay, MLA style requires you to include an in-text citation showing where the quote came from. For a play, this will include the abbreviated title of the play, and the section of the play in which the quote is found.
To be on the safe side, you may want to reference something that is common knowledge. To do so, you would need to track down a copy of this speech and then cite where you found it from such as the website or book. You would use the standard APA format for the type of material you found the quote in. So if you found the quote in a movie, you would cite the movie on your Reference page and put an in-text citation to the movie as an in-text citation next to the quotation in your paper.
