Back in middle school history, they wanted to know who the UK Prime Minister was during WWI, and I couldn't remember so I wrote down James Bond, and got half credit for making the teacher laugh.

in college calc classes, my handwriting was famously quite poor. I'd scribble down some illegible notes and formulas, draw a few pictures illustrating the problem, then come up with a random answer. most of my classes graded work, not correct answers, so if I had an inkling of the right way to do it I could fake it and usually get at least 75% credit for the question.

always hated the questions that make you use the answer from previous questions. always a good time when you get to the end and have a nonsensical answer and have to redo 4 pages to find where you forgot to carry a 1.
