At a New Orleans jazz funeral like the one at the end of this episode, it's customary for the brass band to play a dirge or a traditional gospel melody (such as "Just A Closer Walk With Thee") on the way to the cemetery. "The House of the Rising Sun" would not be played, due to its inappropriate subject matter, and in any case there wouldn't be a singer (with a microphone, no less.) Jinxy and his friends would have known this.

It is very hard to produce a decent sketch of a person and make good drawings when holding a pencil like a chimp.

There is a very visible age gap between Dodds and Jinxy, despite Dodds saying that they were both 5 years old when they first met at school. Actor Robert Goodman (Jinxy) is more than 11 years older than Jason Watkins (Dodds) and if anything Goodman looks older than his years and Watkins younger. Yet there is no make-up attempt to mask this, and make it more credible.

When the singer begins at the funeral, the brass players are not in sync with the soundtrack.

McDonald and Dodds inside Jinxsy's apartment. Find a room with a U.S. route sign 666. Dodds says it's supposed to be 66.

U.S. Route 666 dates back to 1934. US 666 got its name simply by being the sixth designated offshoot of Route 66.

The highway's name was decommissioned 2003 because of many incidents of stolen road signs linked to superstitions based in Christian associations of the number 666 with biblical prophecies of the "number of the beast," with the "beast" being the devil.
