It's not necessary to instantiate Person; changing the last line to 
Person.speaks also works. This indicates that speak is being defined as 
a class method. This can be confirmed if you put a "p self" line in:

class Person
end

p = Person.new

def p.something
  def speaks
    puts 'i speak'
    p self
  end
end

p.something
Person.speaks

which gives:

i speak
Person

How it works is beyond me though.
