It ain't original to The Simpsons.? It's from a story that's over 100 years old and has been reuse dozens of times.? Check out Wikipedia
I enquired of Pat May 8 if he knew of the Simpson episode.? He did not recall.? Schzoid went through his collection, and we handed over a copy
of the Monkey Paw episode af the May Coins show in May.? I've talked to other people generally about Monkey Paw, and those who knew of it
referred to the old horror story.
Also, here's a copy of my post from deeper down the "Messages to Other Patheads," back when Monkey Paw was new.? Happy? Reading:
I was originally gonna just link this up with a copy of 'The Monkey's Paw' by WW Jacobs (1908)'...http://www.americanliterature.com/SS/SS19.HTML
... but I somehow think this link here a lot more appropriate....http://thetravisty.com/Just_Funny/wmv/Simpsons_-_The_Monkeys_Paw.htm
Hope this clarifies
