Think you ruby likes you. Think again. Load it up into any program and you will have trouble displaying anything to the screen.

# Monkeypatching like a boss
class Array
	def do_def(&block)
		self.each do |method|
			Kernel.send :define_method, method, &block
		end
	end
end

# Think you can print anything. You must be stupid
[:print, :printf, :puts].do_def do | *args |
	nice_names = ["pony", "fairy"] # Fill in with your own words
	i = Random.rand(nice_names.length)
	$stdout.puts "I'm not printing anything for you. Do it yourself you lazy #{nice_names[i]}."
