I AM THE TIN MAN

The Introduction actually matches the first video's numbers, with the only difference being the space in "tin man" which wasn't in the video. Also, the tagline's message was backwards, but not the same way of the video messages. The video's numbers had to be put into reverse 1 by 1 for the result to make sense, in this case it was needed to either put them into reverse 2 by 2 or to reverse the decoded text.
