Update (4:45 p.m. EDT): The Harvard Crimson tweets that the class was Professor Matthew Platt's "Introduction to Congress." It would have been awesome if the cheating had been in an ethics class, but this is almost as good.

Original: The interesting thing about Harvard's big plagiarism scandal, which broke Thursday, is that all 125 students involved came from the same course, but the most frustrating thing is that Harvard won't say what course it was. As Bloomberg's John Lauerman reports, the 125 students accused of plagiarism account for half of those enrolled in the spring course, where they're accused of collaborating with each other on take-home exams that expressly forbade it. "A teaching assistant noticed some possible problems on the tests, including evidence that students collaborated on answers or used the same long, identical strings of words," The Associated Press' Jay Lindsay reported. This mystery class must have been plagiarism central. But according to undergraduate dean Jay M. Harris, those 125 kids are the only ones thought to have cheated. It's still the biggest cheating scandal anyone at the school can remember, Bloomberg reports.
