N(exact number to be decided later) ways to relieve your boredom in class

Well friends, a few days back in a certain class ( I shall not mention which just in case some vindictive person shows this blog to the prof or thanks to Google, the prof finds this blog  ), I was getting bored. And I mean REALLY bored. So, I had to figure out a way to relieve my boredom. Instead, I figured out N ways to and i wrote them down at the back of my notebook. They are as follows:-

1. Draw cartoons of the ( prof | any other (living | non-living) entity ) at the back of your notebook. [The expressions used in this sentence strictly conform to the Regular Expressions defined in Papadimitriou's book]

2. Play Snake on your cellphone.

3. Pretend that you are listening to what the prof is trying to say and do some thing else, like write an article on "N ways to relieve your boredom while in class". [For the more mathematically inclined, this sentence can actually be accepted by a Turing Machine built using the Recursion Theorem]

4. Watch the 9 pointers listening to the prof with rapt attention and even TAKING NOTES!!!!

5. Think - Let your imagination wander. Try and find rationale behind every arbit thought that comes to your mind. Eg. :- How can you transform a mere Homo sapiens into a Super Saiyan III. Or perhaps, How you can explain the concept of monorail trains using only a cat, a piece of buttered bread and gravitation. [Try the last question. Its really interesting]

6. Suddenly notice that the prof is apparently speaking in Zulu. [Actually he is perhaps speaking in English, but thanks to your blatant disregard  for his lecture so far, it seems Zulu to your ears]

7. Watch some of your classmates stealthily enter the class after 30 minutes and share a private laugh with your friends.

8. Get frussst of writing this stupid piece, close the notebook and take a little nap.
