Rails' method_missing is a great example of this and awesome to read through for a thorough mind fuck.

Rails doesn't have a method_missing, Ruby does, it copied it from Smalltalk's #doesNotUnderstand:. Rails is a framework, not a language.

Oh come on. I meant how it was implemented with AR

I have no idea what you meant, I can only comment on what you said. Had you said activerecord's implementation of method_missing, I'd have understood, but you said Rails.
