The link I posted is a snippet of the claymation The Adventures of Mark Twain. Whether the film is an actual representation of Clemens ideas and thoughts is not up to me to decide as I have only read only one book of his. I have done some cursory research about Clemens and I did find that Clemens was a Freemason.

About the film. I do not take it as an actual work of Clemens. I take it more as an adaption for kids with a wide range of his works to make it more appealing for younger viewers. I enjoyed the film and this scene particularly.

Now, your questions.

Seriously, I would like an answer to these questions. Is there some information about yourself you're not telling us? Yes, there is a lot of information about myself I am not disclosing, but that goes without saying. I think what you were trying to say, and correct me if I am wrong, was if had some hidden agenda.

No, I dont really have a hidden agenda. I just thought that this subreddit might enjoy the clip.

Do you have a brain injury from Iraq?

No, I do not have a brain injury of any kind. (Accoring, to the best of my knowledge.)

Do you really take that cartoon to be the actual work of Mark Twain?

No, I dont. Like I said, I took it more of an amalgamation of his works, as a sampler of his ideas.
