For many a year, one of my claims to fame was that I had never seen The Wizard of Oz. I never thought it to be a big deal as a kid, I didn't really know what all the fuss was about but as I approached young adulthood people seemed more and more facinated bW the fact that I had never seen it. Whenever the discussion turned to things Oz I always took the opportunity to hijack the conversation with my somewhat unique perspective: that of a Oz neophyte. It didn't take me long to figure out that I could leverage the situation to my advantage by turning the discussion to my incomplete childhood as I certainly could not share rememberances of Dorothy, the monkeys or the Ommpaloompas. It was much easier just to make it all about me.
I still haven't seen it, but people don't seem to care as much.
No Charlie and the Chocolate Factory either.
