Little Jack Murphy

Little Jack Murphy is the ghost of a boy said to have had locker 237, a haunted locker. He turns out to be just one of Fern's stories, although being slightly based on a real student named Jay Mayberry.

After he was assigned the locker, strange misfortunes began happening to him. A black cat crossed his path, he rode his bike into a bush, stepped in wet cement, and got his lunch stolen by a dog. Strange events continued until, one day, he just disappeared.

There is a slight chance that he is a real ghost, as an unseen force  was seen swinging the swings at the playground at the end of the episode.

Trivia

 * His misfortunes are nearly identical to Brain's in "Friday the 13th."
 * His only line was screaming when he crashed into a bush. This scream was reused from Timmy Tibble in "D.W. Rides Again." Coincidentally, both were riding their bikes into a bush.
