That's an... interesting title.
"Pure Comedy" is indeed a YouTube video, but it appears to be a comedy sketch or short film. However, I couldn't find any information about the content of the video without watching it myself (which I won't do, as I'm a large language model and don't have personal preferences or watch videos).
Could you tell me more about the video? What's it about? Is it a clever joke, a witty commentary on modern life, or something else entirely?
And by the way, is John Wilkes Booth a comedian or actor in this case? I'm aware that he was actually an American actor and assassin of President Abraham Lincoln, which might make his involvement in a comedy sketch quite... unexpected.
