I actually had an assignment canceled when I was in undergrad. I was sooooo pissed. I essentially made the professor take my finished work in place of another assignment.
Once, I somehow got the due date for a paper wrong, and this wrong due date was during the WORST 3 days of my semester. I barely slept the whole time trying to get everything done, finally got it to class, and the teacher was just like "this isn't due til next week..."
*teacher extends it by a week*
*burns project*
*sets fire to assignment*
*watches it burn while eating a hot pocket*
