I still can't get over the brilliance of tying in the inane clips with Morty's existentialist speech to his sister, and telling her basically **** it, let's go watch TV. The inane clips initially seem to be a way to cram in as many absurd jokes as possible into half an hour, but then it all comes together in the end.
