   skip_callback :validate, :before, :check_membership, :if => lambda { self.age > 18 }
end

      def skip_callback(name, *filter_list, &block)
        __update_callbacks(name, filter_list, block) do |target, chain, type, filters, options|
          filters.each do |filter|
            filter = chain.find {|c| c.matches?(type, filter) }

            if filter && options.any?
              new_filter = filter.clone(chain, self)
              chain.insert(chain.index(filter), new_filter)
              new_filter.recompile!(options, options[:per_key] || {})
            end

            chain.delete(filter)
          end
          target.send("_#{name}_callbacks=", chain)
