I was in class today, being bored, and started to write some geek jokes on a paper. And then I came up with this one which describes the class I attended when I thought of it

abstract class classes{
    public static int awaitingTheEnd(void);
}

class philosophy extends classes{
    // public... yeah, actually it is - static... the way it keeps your mind - void... because it couldn't be anything else
    public static int awaitingTheEnd(void){
        for(;;);  // the for-ever here describes how long the classes seem to last
        return 0; // The number 0 stands for the number of class I expect to attend
    }
}
