That reminds me of one of the problems I had to do on a 300 level physics test:
blahblahblahblah
blahblahblah
blahblahblahblah
blahblah
Then something goes here that I can't remember exactly but it goes something like this:
blahblahblahblahblah
blahblahblah
I got 7 out of 10 points on that question with a note "you did good right up to the point where you started making stuff up"
