copy in the exam

Two children were writing an exam...
The examiner was very strict,
he wasn't letting them copy
so the 1st child gave the examiner a chit.
the examiner was shocked..
after he read the chit he went and sat down on the chair and
dint get up for the rest of the exam..
after coming out of the exam hall,
the 2nd student asked wat he had written on the chit...
the 1st student said that he had written..
