This scene is from the Hobbit in the chapter "Flies and Spiders".
Bilbo has to save the dwarfs so he starts throwing rocks at the spiders. When all the spiders come at him he gains the courage to sing this:
Old fat spider spinning in a tree!
Old fat spider can't see me!
Won't you stop,
Stop your spinning and look for me?
Old Tomnoddy, all big body,
Old Tomnoddy can't spy me!
Down you drop!
You'll never catch me up your tree!
- J. R. Tolkein's "The Hobbit", Ch. VIII
Sadly I do not have a Bilbo with a red cloak nether a ring at the moment so I have to make do. Also notice the custom ring I made.
Weird thing is that I had some pictures of the spider but I guess I forgot to upload it...
