New school joke

A boy joined a new school. He was 5.

His new teacher asked, "Can you read and write?" he replied that he could write but not read.

The teacher handed him a pen and some paper and told him to write his name. He looked at the paper for a few seconds before scribbling on one of the lines.

"What does that say?" asked the teacher?

"How would I know, I can't read!" exclaimed the boy.
