Nested has_many :through

Hi (Oh my God… he just started his blog post with ‘Hi’),
Did you know that as of Rails 3.1, you can have nested has_many :through clauses in your models? Here is a concrete example to understand what I mean:
class SportSchedule < ActiveRecord::Base
has_many :gamedays
has_many :games, :through => :gamedays
has_many :results, :through => :games # <= You could not do this before Rails 3.1

def has_results?
