The teacher pulls Johnny aside after a test...
“Johnny I have a feeling that you have been cheating on your tests,” she says. “You know I can’t condone cheating.”
Johnny was astounded and asked the teacher to prove it.
"Well,” said the teacher. “I was looking over your test and the question was, 'Who was our first president?', and the student that sits next to you, Mary, put 'George Washington,' and so did you."
“So, everyone knows that he was the first president."
“Well, just wait a minute," the teacher continued. "The next question was, 'Who freed the slaves?' Mary put Abraham Lincoln and so did you."
"Well, I read the history book last night and I remembered that," said Johnny.
“Wait," said the teacher. "The next question was, 'Who was president during the Louisiana Purchase?' Mary put 'I don't know,' and you put, 'Me neither'."
