Ray's mind is toast and it shows on this episode. The man has gone completely senile. He's past the point of no return, it's all downhill from here. 6 months tops before he forgets how to speak entirely. Make sure to tell your friends to tune in to witness a man's brain melt before your very ears. The only other time you get to see someones brain degrade in real time is if they're related to you. 

JK he's fine obviously. Probably just tired. 

Enjoy!
