Hamlet: Whose grave is this sir?
First Gravedigger: Mine sir.
[Resumes singing his ditty]
Hamlet: [Interrupts] I think it be thine indeed, for thou liest in't.
First Gravedigger: You lie out on't sir, and therefore it is not yours. For my part I do not lie ins't and yet it is mine.
Hamlet: Thou dost lie in't to be in't, and say 'tis thine. 'Tis for the dead not for the quick, therefore thou liest.
First Gravedigger: 'Tis a quick lie, sir. 'Twill away again from me to you.
