Which is exactly right -- 'title' is a string and there's no such method.
But you can add one:

class String
   def title_format
      self.split.each{|element| element.capitalize! }.join(" ")
   end
end

puts "what the heck".title_format  #=> What The Heck

You definitely don't want the `print` and `puts` inside your method,
and in your example you're trying to return the method itself, which
is bound to end badly  :-)

HTH,
