This should work with all enumerables:

   module Enumerable
     def rand
       entries = entries
       entries.at(Kernel.rand(entries.length))
     end
   end

I can't seem to get around the `entries = entries' part -- I don't want 
to convert the enumerable to an array more than once. Any ideas?
