Scruffy

Scruffy is the janitor at Planet Express and is the only person working for Planet Express who isn't a primary character. He reads pornography, and believes in his company, which somehow got him to own 40,000 shares of Planet Express while everyone else had 10,000. The other members of staff only see him occasionally, and rarely recognize him when they do. Sometimes he doesn't recognize them, either. Scruffy has indicated that he's been to prison.

Scruffy was originally just a background character seen working various jobs. However they brought him in on the murder scene of Anthology of Interest I because they were running out of non-dead characters. From there his permanent role as the Janitor of Planet Express was cemented when he was brought back in later episodes without changing jobs.

Trivia

 * The first time he appeared, he didn't speak, and his moustache and hat colors were reversed.
 * Scruffy puts cameras up in every room in Futurama Returns
 * A comment made by Fry in The Luck of the Fryrish ("I didn't reveal the clover's location to anyone. Not even to Scruffy!") suggests that the two may have become close friends. But, at the time, this was more likely to be a pun on the fact that everyone always seem not to know who Scruffy is. However, in  Fry is shown to keep two of Scruffy's numbers, vs. one of everyone else's. This seems to extend the joke even further.

 * He had a career at Le Spa.
