Consider a bar with N seats arranged in a line.  A series of fat men
enter the bar but each is too big for one seat, so he randomly picks a
pair of adjacent unoccupied seats and sits on both.  This continues
until there are no longer any adjacent pairs of unoccupied seats at
which point we look at the fraction f of the N seats which are occupied.


Question:  What is the expected value of f (i.e., averaged over the
random choice each man makes on where to sit) as N becomes infinite?
