This is a modified quote from Game of Thrones; the original reads:
You stand in the presence of Daenerys Stormborn of House Targaryen, rightful heir to the Iron Throne, rightful Queen of the Andals and the First Men, Protector of the Seven Kingdoms, the Mother of Dragons, the Khaleesi of the Great Grass Sea, the Unburnt, the Breaker of Chains.
Scranton is a city in Pennsylvania, where I assume Mr. Curtis the physics teacher was born because of this mural and the fact that he likes Philadelphia teams. Mr. Curtis is the soccer coach, and their team has won the state championship multiple times. Momentum is conserved in collisions in physics problems. The Flyers is a Philadelphia hockey team that Mr. Curtis likes. When force is applied a perpendicular distance away from the axis of rotation of an object, you get torque that twists/rolls the object. Mr. Curtis likes telling jokes, which include 'roasts' about students. As a teacher, Mr. Curtis sometimes has to 'break grades,' especially since physics can be a difficult class (although there is plenty of extra credit on tests and grade-raising projects).
