“The lady doth protest too much”

If you’ve ever seen (or read) Macbeth, then you’ll likely remember the scene wherein Hamlet’s mother, Gertrude, watches the staged play-within-a-play and comments on the woman playing the queen. The woman has gone on for some time about how she will never marry again once the poor (and poisoned) king has passed. Gertrude is saying at this point that she doesn’t buy it, and that the queen on stage is selling a bill of goods (basically).
