There are comments in the source of the website, explaining most of what people have asked here, including where he has taught, his organ, mistaking his identity for a football coach and bird watcher, and a plea to not be emailed that Donald Knuth is still alive.
On the other pages there appears to be more information available about passages chosen, and other fun bits. Check it out.
It is satirical. If you go to the main page, at http://www.larry.denenberg.com/ , you'll see this is described as "a celebration of Don Knuth". The jokes require you to understand who Donald Knuth is and what he's done. A premise is that we're in the far future (20002), and some of the details are fuzzy.
It starts with the title. "Knuth 3:16" makes it sound like Knuth wrote one of the books of the bible. Among CS researches, Knuth's works are held in high esteem.
The text "he started life as a college football coach" refers to Knute Rockne, who is shown in the picture. This is a joke on the similarity of Knuth and Knute, with the premise that in 20002 these two famous people have been blurred into one.
Heh, ok, I missed the 20002. I dunno, if any institution hangs around that long (including some form of www hosting for the OP), maybe Stanford has a chance, if not a copy of wikipedia or Knuth's books.
While we’re at it, Knuth has also released a book (which is just transcripts of 5-6 lectures) wherein he discusses the 3:16 project: "Things a Computer Scientist Rarely Talks About"
>"He was an enthusiastic musician, though exactly which was his instrument is a subject of some dispute (the most likely candidates are the accordion, jew's harp, and flugelhorn)."
It seems the author missed or forgot the legendary pipe organ.
