The You Shall Not Pass Stamp lets teachers fail their students with a little Lord of the Rings humor thrown in. This hilarious imprint would be the best way to find out you failed a test because at least you know your teacher has a good sense of humor.
Perhaps the most famous line from the Lord of the Rings trilogy other than "my precious," the "You Shall Not Pass!" line was shouted by Gandalf as he faced the demonic Balrog. Gandalf the Grey then fell into a pit of darkness and emerged as Gandalf the White. Now this classic line has been modified to let teachers have a little fun with their students.
