Little is known about the history of the group. The earliest recorded mention was in a 1973 book titled 1001 Stupid (but true) Student Theories, published by two enteupenurial college students. The book claims that, "Our teachers are always trippin'. One sec, they're here, then they're gone for fifteen minutes, then they're back, often with what look like claw gashes across their faces, almost as if they're in some sort of 'Time Force Defense League' or something. Most people don't seem to notice but me and Jake [the book's co-author] started gettin' the heebie-jeebies."
