Grading Hell

This is one of the two times of year profs call "grading hell." With large stacks of papers and short amounts of time, everyone is stressed, everyone is exhausted, and grades are due. Family is pushing for more time because things need to be done in preparation of the holidays and you've got more work to do than hours to do it in. And then we get approached and have exactly this conversation repeatedly: What's the worst excuse/plea you've ever gotten/heard of?
