Seriously now, school rebels ...what you do is fun ...but inno eventually it's silly ...
the best way to have fun is to have an open discussion with an open minded teacher and make jokes in the meanwhile ...
That way, you waste the course ... and you have fun ! REAL FUN !
And you'll be learning something as well .. Inno trying to be cool is sometimes not COOL !
That's the way I see it ...
Fun is when you know as a class how to direct the course ...to avoid getting bored .
The playing cards thing is Nice by the way
too bad it's like your calling to be exceuted if done in my school ...
