This reminds me of the Prologue to Pyramus and Thisbe in A Midsummer Night's Dream. Quince says:
'If we offend, it is with our good will.
That you should think, we come not to offend,
But with good will. To show our simple skill,
That is the true beginning of our end.
Consider then, we come but in despite.
We do not come, as minding to content you,
Our true intent is. All for your delight
We are not here. That you should here repent you,
The actors are at hand: and, by their show,
You shall know all that you are like to know,'
I suppose it's sort of in the realm of the metatheatrical, but a lecturer made an interesting point about this piece the other day. Generally Shakespeare would have left his plays unpunctuated and the job of punctuating would have been the editor's. Anyway, the lecturer said that this was perhaps the only text we can be certain that Shakespeare punctuated himself because the humour comes from the misplaced fullstops and commas. We looked at the piece without any punctuation and it's possibly to punctuate it in such a way that it's garbled but means the opposite of what it means with the punctuation as it is now. Anyway, food for thought and all that!
