Wikipedia: Gandalf
Gandalf is a protagonist in J. R. R. Tolkien’s novels The Hobbit and The Lord of the Rings. He is a wizard, one of the Istari order, and the leader and mentor of the Fellowship of the Ring. Tolkien took the name “Gandalf” from the Old Norse “Catalogue of Dwarves” (Dvergatal) in the Völuspá.
(...)
The Balrog reached the bridge. Gandalf stood in the middle of the span, leaning on the staff in his left hand, but in his other hand Glamdring gleamed, cold and white. His enemy halted again, facing him, and the shadow about it reached out like two vast wings. It raised the whip, and the thongs whined and cracked. Fire came from its nostrils. But Gandalf stood firm. “You cannot pass,” he said. The orcs stood still, and a dead silence fell. “I am a servant of the Secret Fire, wielder of the flame of Anor. You cannot pass. The dark fire will not avail you, flame of Udûn. Go back to the Shadow! You cannot pass.”
J. R. R. Tolkien, The Fellowship of the Ring

There’s an evil part of me that hopes a college professor somewhere dressed up as Gandalf for class today, gave a pop quiz, and loudly proclaimed, “You shall not pass!”

Anytime I think of Gandalf fighting the balrog I think back to my first day of my capstone class when Mr. Dr. passed out the syllabus and it had the “you shall not pass” meme on the last page.
