Topic: "Untimely Events"
Lewis Carroll taught Frodo that an "Unbirthday" was a celebratory event, far beyond the more conventional "Birthday." Frodo tries to mark every "Unbirthday" with the best product of the Miller Brewing Company, or with something that makes him recall the few Russian words that rhyme with "Stolichnaya." Those few minutes of time are for Frodo, and in consideration of his daily trek to Mount Doom.
A recent spell of very warm weather on the shores of the Thames brought about a very strange event. Big Ben, the landmark London clock renowned for both its' chimes and its' accuracy, stopped ticking for 90 minutes. The 147 year-old clock, for no explainable reason decided that the warmest day in London since 1953 should be marked by a halt in the passage of time.
The conspiracy theorist in Frodo questions the 90 minutes unmarked by history. Perhaps an alien intelligence suspended the mind of man in order to mask some devious plan to assimilate the Citizens of Middle Earth. Is it possible that the Government implemented some new and underhanded effort to "plant" weapons of mass destruction in an Iraqi sewage treatment facility, and they put us all to sleep while they did so?
All we know for sure is that there were 90 minutes for which Londoners have no record. Frodo's belief is that Ann Coulter must have been in London that day. That is, indeed, a face that can stop a clock.
