A student inquired: "How powerful is Tolkien's ghost?"
Very powerful! The truth is, members of the Tolkien Society in Oxford evaluated the output of supernatural energy at his grave during the last Hobbit film premiere. 30 cm above his grave, a peak ectoplasmatic activity of 4.7 megageist was measured! To compare, a simple poltergeist puts out about 300 to 500 kilogeist.
Here is rare television proof of Tolkien's ghost shooting blue will-o'-the-wisps at Jackson during the oscar ceremony. Unfortunately, Jackson remained unimpressed. He must have literally taken a garlic bath before.
