Bishop Garrigan High School is an all-boys high school with maroon and gold uniform colors. Frank Heffley wanted to send Greg there which only appears in the online version. However Greg didn't wanted to go there as it was all-boys and wanted to go to Crossland High School. On an open night, Frank was waiting for Bill Walter to move his van, after he saw the folder in Frank's hands he said he also went to the school. This caused Frank to instantly change his mind, and making Greg realize Bill got him out of going to Bishop Garrigan. It is based on a school which Frank went to.
