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.
