Back in 49 BC, Julius Caesar was a mere governor commissioned by the Roman Senate to oversee a portion of the empire that stretched from Gaul to Illyricum (pretty much most of today’s Europe except Italy). When his term of governorship ended, the Senate ordered Caesar to disband his army and return to Rome. Whatever you do, Julie baby, don’t bring that army across the Rubicon River for that is treason and insurrection and very bad manners. Oh, and the punishment is death.
Caesar may have misunderstood for didn’t he just up and cross the Rubicon into Italy on January 10. His biographer suggests that he was under the control of a supernatural apparition (the Devil made him do it). Willful or not, Caesar is said to have shouted “alia iacta est” as he and his merry men waded across the shallow river (or ‘the die has been cast,” certainly more dramatic in Latin).
Crossing the Rubicon was a declaration of war, but instead of arresting Caesar the Roman Senate fled Rome in fear. Caesar, far from being condemned to death, became dictator for life. Sometimes it’s good to cross the Rubicon. Crossing the Rubicon has endured as a phrase meaning passing a point of no return.
The Hole in My Record Is Bigger Than the Hole in Your Record
RCA Victor it might be said crossed the Rubicon when on January 10, 1949, it introduced a new kind of record — a vinyl disc, just seven inches in diameter with a great big hole in the middle, the 45 (referring to its revolutions per minute). The 45 replaced the big noisy shellac disc that rotated at a breakneck 78 rpm. The first 45 rpm single was “Peewee the Piccolo.” Remember it?
The Bun Knows
On January 10, 1984, 81-year-old Clara Peller first asked the question for which she would become famous:
Wretched Richard's Almanac 
Not too long ago I came across one of those round plastic doohickeys that you pushed into the middle of your 45 so you could play it on your old turntable.
Recently I saw a notice on my computer that one should keep a ring pull from a soda can in their wallet for emergencies (supposedly thousands of life saving usages).
I am still looking for another use for the plastic 45 doohickey.
I am sure you have at least one.
