Girls Rule!

Girls Rule was a comic founded by Tabitha Cutter and Lisa Russel that Greg Heffley found and read. The comics shows two girls, probably based off of the authors themselves, saying "Girls rule!" after a boy trips. There was also a Girls Rule comic in the Do-It-Yourself Book. Greg deemed this comic inferior to his own and listed it under a section of the book where he posted comics that would most likely fail against his. There are only two known Girls Rule comics (one in the first book and one in the 'Do It Yourself' book)
