Is That Bill Shakespeare Over There?

So recently, I was listening to the reading of a play. Now, this play has been produced before. And one would assume it has been edited and re-edited. I had to share with all you faithful Hootenanny patrons something I ran across in the script.

The following appears 3/4 of the way through the story. The 4 main characters are the only ones on stage and all have not only been introduced at this point but present throughout and crucial to the play's action.

In the middle of the dialogue, the Speaker is ranting and raving and listing faults of the other characters when the stage directions direct the Main Character:

Blah...blah...blah, emphatic dialogue (Pointing specifically to someone) blah blah blah....

Gotta love good writing.
