Other mistake: When Emma Watson says "get wasted all the time", her British accent is very obvious, especially when she says "all."

Factual error: In all of the cafeteria scenes, the food pyramid posters that can be seen on the walls are the updated 2011 versions, not the ones they would have had in 1991 and 1992.
Trivia: Brad lied to his friends about how his face got banged up, saying he was jumped by some kids outside of the "O." The "O" refers to the Original Hot Dog Place, which was located close to the University of Pitsburgh's Cathedral of Learning and was very popular among the students and others. It had been in operation for about 60 years but closed on 4/18/20 due to the Coronavirus pandemic. Pittsburgh native Mark Cuban (owner of the Dallas Mavericks) tried to buy the "O" but it was sold to a chain. (01:09:52)
