I Got A Rock
Mike talks about this all the time. Charlie Brown goes trick or treating with his friends and they get great candy and he gets a rock.
Because I never saw this as a child, it seems strangely unclimatic to me. I was never allowed to watch the holiday specials on TV when I was a kid because we were Jehovah Witness. Watching them as an adult just isn’t the same.
I guess I missed out on this piece of the collective unconscious.
