Lucky Lefty Wilbur's Right

As the story goes, Friday night, LLW grasped a wine glass with his right hand.  Somehow that wine glass popped it's stem while LLW set the darn thing down.  The questions are....How much wine was in the glass at the time and how much wine was not in the glass at the time?  The answer might determine the amount of force that a wine glass hits the counter and then breaks into pieces leaving Lucky Lefty with blood squirting in all directions.  Consequently, when we arrive in Lyle, LLW has bandages on his right hand strummin' finger and bandages on some of the other digits.  Lucky remains to be Lucky.  Rock and roll music has got to go on.
