Fred is a minor character in Calvin and Hobbes. He appeared in a single Sunday strip. In it, Calvin acted out a Spaceman Spiff fantasy at his school, where he hid from Miss Wormwood in the teachers' lounge. Out of at least four staff members, perceived by Spaceman Spiff as extraterrestrial monsters, one exclaimed "Who was That?" in reference to Calvin's pop-in. He was then referred to by another employee as Fred.
