"But for these medd'ling kids and this their dog."

RJ points us to the Lost Quarto of Hamlet:

This recently discovered folio edition of "Hamlet" follows other known versions closely until Act V, Scene II, where it begins to diverge at line 232, as will be seen:

KING ...`Now the king drinks to Hamlet.' Come, begin,
And you the judges, bear a wary eye

Trumpets sound. HAMLET and LAERTES take their stations

HAMLET: Come on, sir.
LAERTES: Come, my lord.

Enter FRED, DAPHNE, VELMA, SHAGGY, AND SCOOBY

DAPHNE: Wait!
SHAGGY: Stop the fight!

HAMLET and LAERTES put up their foils

KING: I like this not. Say wherefore you do speak?
FRED: Good lord, I pray thee, let thy anger wait.
For we, in seeking clues, have found the truth
Behind the strange events of latter days. ...
