A student opens a copy of Euclid’s Elements and a dark spirit emerges from the pages of the book.
Teacher-Genie: I am the teacher-genie. I will grant you one educational wish.
Student: What? Really?
Student: I can have whatever I want?
Teacher-Genie: That’s the deal.
Student: I want an A in Geometry class.
Teacher-Genie: It is done. You have an A in Geometry class.
Student: Whoa. Awesome. This is fantastic news. Now I’m at the top of my class.
Teacher-Genie: That’s… not exactly true.
Student: (confused) What? Why?
Teacher-Genie: All the other students in your Geometry class have A++++’s. You are actually at the bottom of your class.
Student: (outraged) This is a horrible miscarriage of justice.
Teacher-Genie: I gave you an A, though. I gave you exactly what you asked for. Check your report card. You have an A in Geometry.
Student: But now it doesn’t mean anything!
Teacher-Genie: It never meant anything.
