Hamlet, Put Down the Skull.

So I saw somebody carrying a skull as part of her Halloween costume, and of course I had to come up with some jokes about Yorick, being quite chap-fallen, could not enjoy the Reese’s Pieces he did love so very much.  So of course I had to pull up Hamlet’s speech to get my quotes right.  I go to the MIT (Moby) version, because it’s the easiest to search:

And I thought, “Wait… there’s a stage direction that tells him to put down the skull? That seems oddly specific for a play that rarely states stage directions beyond who enters, exits and dies.”

So I go look it up in the First Folio, as you folks have taught me to do:

Nope! Not there. I’m not surprised, I get that various editions get conflated over the years.  But the thing is, I checked two quartos as well as Second and Third Folio, and I can’t find it in any of those, either.
Anybody know when this got added?  And possibly the more interesting question, why? Was there an edition where somebody went in and really got specific about such things, for some reason? Maybe David Garrick kept forgetting to put down Yorick and would end up carrying him through the rest of the scene until a director got the idea to write it into the script 🙂
