A vast repository of useless knowledge

Nearly 10 years ago, a friend of mine would frequent the low-key bar in the restaurant where I worked, drinking Belvedere martinis and working on the daily crossword.  I was always around to supply arcane knowledge, from the recesses of my brain, to help fill in the boxes.  One day he told me, "You know, you're really a vast repository of useless knowledge."  I laughed hysterically.  Suddenly, today, it occurred to me that this was a fabulous title for a blog.
