There was a university in New England where the students operated a “bank” of term papers and other homework assignments. There were papers to suit all needs. You had your choice of papers for an A-grade, B-grade, and C-grade.
A student who had spent the weekend on pursuits other than her assignment, went to the bank and took out a paper for a C-grade. She went home, retyped it, and handed it in.
In due time she received it back with the grade of an ‘A’. The professor left the following comment, “I wrote this paper myself twenty years ago. I always thought it should have received an A, so now I am glad to give it one.”
