We've all taken tests where we know before hand that there is no way you'll pass. Maybe you never showed up to class, maybe you just didn't read the material. The point is that you know you're going to fail. At this point it is your responsibility to at least make the test entertaining. You still fail, but at least you get to fuck with the teacher.
Some Examples:
-Every 5 min. stand up, collect all your things, move to another seat, continue with the exam.
-Try to get people in the room to do a wave.
-Puke into your exam booklet. Hand it in. Leave.
-Take 6 packages of rice cakes to the exam. Stuff at least 2 rice cakes into your mouth at once. Chew, then cough. Repeat if necessary.
-Masturbate.
-From the moment the exam begins, hum the theme to Jeopardy. Ignore the instructor's requests for you to stop. When they finally get you to leave one way or another, begin whistling the theme to the Bridge on the River Kwai.
-Do the exam with crayons, paint, or fluorescent markers.
-Tailgate outside the classroom before the exam.
-Fake an orgasm. When interrupted, apologize, and explain that question #__ moved you, deeply.
Alright, now who has some other good ideas?
