A great answer to give in math class when a teacher asks you a question to make sure you are paying attention, and you don't know it because you really weren't paying attention.

Great because it is more likely to be the right answer than any other number. Also, even if you're wrong, everybody will think it was just a joke and you will come out on top.

Do not try in other classes or you will look like a dumbass.
