Subject: How to reopen the puts method

I am looking for some additional detail regarding the puts method.  Hows
does the basic puts method work?

module Kernel
  def self.puts text
    $stdout.puts "New_Text"
  end
end

# the following code doesn't actually call the Kernel puts method I've
redefined.
puts "Hello, World!"

# however, this code does.
Kernel.puts "Hello, World!"

I would like to insert a debug flag into the basic puts method and
suppress the output unless a flag is true.  Something like this...
(except this doesn't work)

module Kernel
  def self.puts text, debug=false
    $stdout.puts text if debug
  end
end

puts "Hello, World!", true

Any ideas?
