Badges?

 
A trio of bandits confront a miner packing out his gold. They claim to be Federallys (police) but the miner is suspicious and asks to see their badges. “Badges? We ain't got no badges! We don't need no badges. I don't have to show you any stinkin' badges!” With those words Alfonso Bedoya achieved screen immortality in his role as the Mexican bandit “Gold Hat” in John Huston’s The Treasure of the Sierra Madre. 

Shakespeare belies his own words

Tomorrow, and tomorrow, and tomorrow...
Shakespeare may have reached a dusty death described in the pessimistic passage below but his work lives on and contradicts the "signifying nothing" phrase.

"To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow; a poor player,
That struts and frets his hour upon the stage,
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing."

--From Macbeth (V, v, 19)
