Here, thou incestuous, murderous, damned Dane,
Drink off this potion. Is thy union here?
– William Shakespeare
Hamlet, Act 5, Scene 2. Hamlet to Claudius, giving him his own cup of wine with the poisoned pearl to drink. Hamlet puns sarcastically on the word "union," referring to the pearl the King had offered him as a prize, and also to Claudius’ incestuous marriage with Gertrude.
