Subject: How do I catch a missing method on a passed block?

I would like to invoke method_missing on baz in this code;

x = Foo.new
x.bar { baz }

I tried the following, and although the method is added to the proc
objects singleton class, the method_missing method never gets called.
Is there any way to achieve this? My current code (that doesn't work)
is below;

class Foo

  def bar(*values, &block)

    if block_given?

      class << block
        def method_missing(m, *args, &block)
          puts "missing #{m}"
        end
      end  

      block.call

    end  
  end
end
