Subject: How to intercept all function calls of a object?

What I want is something like this:

class HelloBye
  def hello
    puts "hello"
  end
  def bye
    puts "byebye"
  end
end

a = HelloBye.new
a.extend #add an intercptor to a
a.hello

Then I can get this kind of result:

call method hello of class HelloBye
hello
return from method hello of class HelloBye

And similar thing for 'bye' and other methods if existed in object a.
