"There Was A Law School.." joke
There was a law school where students operated a "bank" of papers that were assigned from time to time. There were papers to suit all needs, and, as it would look odd if an average student suddenly handed in a brilliant essay, there were papers for an A grade, B grade and C grade.
A student who had spent the weekend on pursuits other than his assignment, went to the "bank" and as his course was a standard one he took out a paper for a inconspicuous C, retyped it and handed the work in.
In due course he received it back with the professor's comments "I wrote this paper myself twenty years ago. I always thought it worthy of an A, and now I am glad to give it one!"
