Nice little play on probably the most famous scene from Lord of the Rings. Gandalf telling that fire-breathing, horned, devil beast that he shall not pass, allowing the crew to get to safety. Put in modern times, Gandalf is the stop light and that beast (or mouth-breathing a**hole who’s been riding your ass for 15 blocks now) is going to have to stop because of the power of the white wizard.
If you’re a LOTR fan, this You Shall Not Go T Shirt is another terrific addition to what I imagine is an ever growing collection of paraphernalia. I would suggest if you want to make your collection legit that you purchase this shirt from Snorg Tees right now. It’s the right thing to do to keep moving the needle on your ultimate fandom. It’s not hording if it’s all meticulously themed.
