Classroom design

One day the teacher was talking to her students about how they would design the classroom.

Little Anna says: "I would paint the walls white and put flowers on them so we feel like we are in nature."

Little John says, "I would put some math exercises on the wall. I think that would be cool."

Little Peter was playing with his pencil and didn't seem interested in the subject at all, so the teacher went up to him and asked: "Peter, how would you have designed our classroom?"

Little Peter looks around the classroom and says confidently, "I'd paint the walls neon green, the damn ceiling would be neon yellow, and then I'd put a f..king red stripe across it."

"Peter!!", the teacher exclaims, "where did you learn that kind of language, we don't use such words here, go to the principal's office right away!"

Little Peter calmly walks out of the classroom and goes to the principal's office.

After a while the principal comes out and sees little Peter sitting in front of his office so he asks him: "Peter, are you having trouble again? What happened this time? Come into my office and tell me what happened."

Little Peter comes in and starts telling the principal what happened: "Well, the teacher asked us how to design the classroom so I said I'd paint the walls neon green, and then the damn ceiling neon yellow, and then I'd put a f..king red stripe across it..."

The principal interrupts him: "I understand everything, Peter, but why on earth do you need that f..king red stripe across the damn ceiling?"
