In case you missed it in the comments, it now appears that both Iamaphoney and YouKnowMyName231 are using the same background for their respective YouTube pages.
I thought that the two of them were working independently. They have two very different styles. YouKnow just emerged recently, so I thought at best he/she was someone either inspired by Iamaphoney or someone who thought they could do it better. I started to wonder though when YouKnow demonstrated that "The Fireman is no Mason" was an anagram for "I am the risen son of man." Iamphoney never stated that, but he has used that text from the official Fireman web site many times in his videos and the concept certainly goes with the many Christ-like images from several of his videos.
So what are they trying to say by using this background? Are they working together? Are they one in the same? Is one of them trying to mess with the mind of the other? Are they trying to throw us off or put us on the track? Is there something special about Jupiter?
I have one more observation about that background. The file name of the background of both sites is "20010115CrescentJupiter." I said to myself, "Hmm, I wonder if 20010115 could be referring to the date January 15, 2001." We have to use the U.S. date format. So I checked Wikipedia to see if anything significant happened on January 15, 2001. Guess what? Wikipedia went online on January 15, 2001!
