Seinfeld-based Ruby delegation and dynamic method definitions

gistfile1.txt

# The Class
class CastMember
  
  # The Delegate Method
  def get_mad_at(target)
    puts "#{name}: What do you think you're doing, #{target.name}?"
    target.make_target_of self
  end

  # The Output
  def make_target_of(aggressor)
    puts "#{name}: #{catchphrase(aggressor)}"
  end

  # The Dynamic Method Definition
  def initialize(name, &block)
    @name = name
    define_singleton_method(:catchphrase) do |aggressor, &block|
      yield(aggressor)
    end
  end

  # The Getter
  def name
    @name
  end

  # The Setter
  def name=(name)
    @name=name
  end
end

# The Setup
jerry = CastMember.new "Jerry" do |aggressor|
  "What is the deal with that #{aggressor.name}?"
end
newman = CastMember.new "Newman" do |aggressor|
  "Never mess with the post office, #{aggressor.name}!"
end
george = CastMember.new "Costanza" do |aggressor|
  "I'm on the edge, #{aggressor.name}!"
end
kramer = CastMember.new "Kramer" do |aggressor|
  "#{aggressor.name}, #{aggressor.name}, #{aggressor.name}!!!"
end
elaine = CastMember.new "Elaine" do |aggressor|
  "(Pushes #{aggressor.name} in the chest.)"
end

# The Drama
kramer.get_mad_at jerry
elaine.get_mad_at george
jerry.get_mad_at newman

What is the deal with Ruby?

jerry.send :define_singleton_method, :joke do |topic|
puts "What is the deal with #{topic}?"
end
