I think you want puts array[rand(array.size)], otherwise the last 
element won't ever be used.

------------------------------------------------------------ Kernel#rand
     rand(max=0)    => number
------------------------------------------------------------------------
     Converts _max_ to an integer using max1 = max+.to_i.abs+. If the
     result is zero, returns a pseudorandom floating point number
     greater than or equal to 0.0 and less than 1.0. Otherwise, returns
     a pseudorandom integer greater than or equal to zero and less than
     max1.
