I am so tired of people misquoting this famous phrase from Hamlet.
When Hamlet asks his mother Queen Gertrude how she like his play, The Mousetrap, obviously tweeked, she says:
The lady doth protest too much, methinks. – Hamlet III, ii, 230
Also, let’s try to use it correctly.
Say it a few times outloud to yourself, to get it into your ears.
Also, that "protest," here, doesn’t mean "object to". It means "make a strong claim" about something. We still have that meaning in English "protestation".
What Gertrude means is not that the lady in Hamlet’s play within the play, is objecting to something or denying something. Rather, that she is making far too enthusiastic positive statements.
And don’t add useless syllables like "protestest" or "methinketh" or other stupidities.
