Summary of Skit
Tired of having everyone snooping through your stuff? Then you need Gandalf's 3-ring binder!
(A kid gets knocked over by another kid, causing the stuff to fly out of the kid's binder.)
Kid: Oh, I wish I had a sturdier notebook!
(Scene goes to the top of a mountain.)
Gandalf: One ring to rule them all, and three rings to bind them. Introducing Gandalf's 3-Ring Binder! Forged at Mount Doom in the fires of the custodian's office, the 3-Ring Binder is perfect for organizing you notes, homework, and magic scrolls. And every time you snap it shut, (The kid sees his 3-Ring Binder turn invisible.) it dissappears!
Teacher: Where's your homework?
Kid: It dissappeared!
Teacher: Likely story.
Gandalf: Plus, once you get a 3-Ring Binder, everyone will want one! From Ringwraiths...
Gandalf: To that creepy kid in science class.
Gollum: Give me my precious!
(The kid gets knocked over by a Ringwraith.)
Gandalf: Gandalf's 3-Ring Binder! Look how sturdy it is.
