# method missing fun to fake class methods

class Foo

  def tell(something)
    puts something
    puts yield
  end

  def self.method_missing(name, *args, &block)
    if instance_methods.include? name
      foo = Foo.new
      foo.send(name, args, &block)
    end
  end
end

Foo.tell "moo" do
  "moo"
end
