I'm trying to remember a movie that I watched at least 8 years ago. I don't remember much about it, unfortunately. What I do remember is that the main character was a teacher at a high class school, and was in charge of a trivia contest or something. He caught his favourite student cheating by writing the answers on his arm (I think, for some reason, the student was wearing a toga at the time, if that helps). He then trips the student up by asking the question "who was <outlandish name>", referring back to a quote that he had said on the first day of class. Then, years later, that student becomes successful, and decides to get everyone together to do the trivia competition again. And again, he cheats, this time by being fed the answers through an earpiece. The teacher then catches him out again by asking the same question "who was <long foreign name that I can't remember>". That's all I remember about this movie, and it's been driving me crazy trying to figure it out. Can you help?
