Bishop Garrigan High School

Bishop Garrigan High School is an all-boys high school which has maroon and gold as the official colors for the required school uniform. It's only in the original online version and it's mentioned that Dan, the son of Frank's boss at work, Mr. Swann (called Mr. Warren in the books and the movies), goes to the school. Greg acknowledges that Bishop Garrigan probably is a good school, but his issue with it is how it's a boys-only high school.

Frank was planning on enrolling Greg at the school once he got done with middle school, but while waiting for Bill Walter to move his van, Bill noticed the folder in Frank's hands and revealed he's a former student at Bishop Garrigan High School—Frank was shocked by this and ultimately decided not to enroll Greg at the school.

Trivia

 * Since it's an all-boys school and has a required uniform policy, it's most likely a private school—even nowadays, many private schools still accept only male or female students and many private schools also have a required uniform policy.
 * There is an actual high school called Bishop Garrigan High School—it's located in Algona, Iowa.
 * Unlike the school of the same name in the online version of Diary of a Wimpy Kid, the real-life BGHS is a coed-school (meaning they have both boys and girls) and it also covers middle school in addition to high school. The real-life BGHS is also a religious private school (specifically Roman Catholic), but it's also possible the BGHS in the online version is also a religious private school.
