How does Shakespeare start the play "Romeo and Juliet" so that he gains the attention of the "groundlings?"

In the Prologue, Shakespeare gives a short, concise summary of the story behind the play to capture his audience's attention.  He uses emotion-charged words in his delivery, describing "the fearful passage of their death-marked love" (line 9), and in the last two lines speaks directly to the audience, telling them that they should listen carefully ("with patient ears attend" - line 13) to the dramatic tale about to be enacted.
