Brick

In a class, a teacher showed the students a brick and said,"Now everybody will
tell me what you think about when you see this brick.""I think of our heroic
toilers who build communism using such bricks," one student said.
"Good. Now you, Sveta."
"I think about our heroic forefathers who used such bricks as a weapon when
they fought on barricades during the Revolution."
"Very good. Now you, Peter."
"I think of a cunt."
"And why, permit me to ask, are you thinking of such a thing when I
specifically showed you this brick?"
"I just always think of it."
