The concept of the episode "Sore Eyes" is very similar to "My Peeps", an episode of Cartoon Network's other show ''The Grim Adventures of Billy and Mandy'', in which both episodes are about a redheaded boy who has trouble with his eyesight, but after a laser eye surgery, he starts to see something utterly disturbing, and ends with one of the most disturbing pieces of imagery known to man.
Production code is 406.
Last appearance of Douglas E. Mordecai III in this episode in production.
Although these episodes were aired in 2003, there were made in 2002 according to the credits.
