That which is uttered that doth sound of the Bard but cometh not of his pen.
(Fake + Shakespeare = Fakespeare)
1) Fakespeare of the punning style, such as this Richard-III-esque line: "Now is the winter of our disco tent."
2) Fakespeare of the "damn, I've forgotten my line" style, such as: "The king wears heels; yet O! I know not why."
