The school principal is walking along the corridor

and sees a ten-year-old strolling in the opposite direction, smoking a cigarette and drinking beer from a bottle.

The principal is outraged and cries out:

— What's going on here? Why aren't you at class? And how dare you smoke and drink alcohol at school? What class are you from?

The kid calmly blows smoke into the principal's face and says:

— Bourgeoisie.
