Jay & Silent Bob found out, in Dogma, to their dismay, that the Chicago suburb-town of Shermer, Illinois, was actually an entirely fictional place, dreamed up by the master of the 80s teen comedy/drama - John Hughes.
Many of the films he wrote or directed were set in the same fictitious universe. In a 1999 interview he revealed the scale of this "Shermer-verse". 15 years worth of notebooks detailed how Ferris Bueller (FB's Day Off) was friends with Sam Baker (16 Candles), John Bender (The Breakfast Club) lived three doors down from Del Griffiths (Planes, Trains & Automobiles) and so on. What a shame his untimely death meant we did not get to see this 'verse expanded upon.
The bulldog mascot was briefly mention in Ferris Bueller's Day Off and the names at the bottom of the shirt are all Shermer High School alumni from the films:
Home Alone, Ferris Bueller's Day Off, Pretty In Pink, The Breakfast Club, Uncle Buck, Some Kind Of Wonderful, Sixteen Candles & Weird Science

On a brisk spring morning in 1984, a group of delinquents came together in the school library to serve detention. This t-shirt features the school's name, Shermer High School, and the year that it all went down. Each one of us is a brain, an athlete, a basket case, a princess and a criminal.
Fake illness, fool parents, ring the school, fool the Dean of Students, pick up best friend (in his dad’s car), collect girlfriend, fool the Dean of Students, drive to Chicago, get up to crazy antics, fool the Dean of Students, drop off friend (destroy his dad’s car), get home in time to beat parents (and jealous sister), fool the Dean of Students one last time. Relax.
