My friend came up with this on her Facebook profile:
Five fun things to do in an exam hall when you have no hope of passing:
1. Bring in a large cumbersome idol and pray to it often. Consider making a small sacrifice.
2. Flip over the paper, look horrifed and say "HUH?" really loudly, before proceeding to write the answer. Repeat for every question.
3. Quietly and with an air of great industry, eat your paper. Then raise your hand and ask for another one. When asked what happened to the paper reply remorsefully "I eated it".
4. Place a radio antenna over your head and point it at the person beside you. Act as though you are listening intenly before jotting down the answer. Consider making buzzing sounds.
5. Set free a small rodent on your desk and vehemently deny its existence.
