They usually have word limits, which are a total bitch to adhere to - if it isn't too short it'll be miles too long.
They will produce much bitching and complaining and procrastinating (bubbleshooter.net is a particularly good tool for this).
The one positive thing about them perhaps, is the sheer feeling of relief that occurs when the last word is typed and all word counts are adhered to. Who cares if it makes sense or answers the question?! It's finished. The only feeling quite like it is that wonderful feeling that occurs when you finally go to the toilet after being desperate for ages.

3. "I deserved a better grade than THAT!!!"
4. I am procrastinating right now, as I have a 1500 word assignment due in in about 10 hours, and I've only written 250 words. I have a massive mug of coffee at the ready!
Another Guy: You mean the ass-ignment?
