Exam and test jokes and humor

Teacher: I hope I didn't see you looking at Fred's test paper.
Pupil: I hope you didn't see me either !
Teacher: You copied from Fred's exam paper didn't you ?
Pupil: How did you know ?
Teacher: Fred's paper says "I don't know" and you have put "Me, neither"!
Great news; teacher says we have a test today come rain or shine.
So what's so great about that ?
It's snowing outside !
