No it is not the fact that the method call is not within another method 
call that is tripping me up.  It is that I cannot get it to work for me.

Consider the following code:
####################################
module Test

  def self.include(base)
    base.extend(ClassMethods)
  end

  module ClassMethods
    def call_me
      puts "Class method"
    end
  end
end

class Tester
  include Test
 call_me#toy.rb:23: undefined method `call_me' for 
Tester:Class(NoMethodError)
end

Tester.new
###################################

yields the following results:
toy.rb:24: undefined local variable or method `call_me' for Tester:Class 
(NameError)

Again I am assuming my 'call_me' is equivalent to my originally 
referenced 'skip_before_filter'.

Thanks,

Cris
