Put z=0

Actually I got a comment from Faris regarding "z=0". So a narration came to my mind.
The story was narrated to me by Mishal during ma college days (2004-08) .
(For best results , the story should be narrated by Mishal (the Narration Dude!)

Mishal was in the examination hall writing his Engineering Mathematics -1 university exam. Maths was always the subject Mishal hated. He needed 40 to pass the exam . He completed some questions. But one question was lukin a bit difficult. Question to find the value of x,y and z(The simplest question I know ). To his notice came a guy called Arshad(The hero of the story ), his school pal , sittin next to him , doin the same question. Mishal was happy seeing his answer sheet. He called Arshad.
In a very silent voice Mishal calls
Mishal: Arshad ......Arshad ...
(Arshad s too busy solvin te queestion )
Arshad turns to Mishal
Arshad : yeah ... Im busy ..wot happened (silently )
Mishal points the finger to the answer sheet and gestures to turn the answer sheet to him .
Mishal : Idu sheri aano ? (Is this answer right ).
Arshad : (makes gesture like a mathematician) definitely man!
Mishal : Ok!
Mishal starts copying ..very fast .. like a thee vandi (fire engine )
when Mishal reaches the last part of the answer where we people write the answer in the form x=something , y = somethign and z=somethign . He founds out the answr was
x=10; y=12;
(Somehow Arshad messed up with z in the calculations.. Its Calicut University .. People always find them in a difficult situation..)

He notices that thers no "z". He then turns to Arshad

Mishal : Arshad ...Arshad..
Arshad : waves his head .. and ask ..Wot happened ?
Mishal : mairaaaa.. "z evide poeeeee"(whers the fuckin z)?
Arshad : (thinks for 5 secs ) ... Put z=0;
Mishal : ok!

After coming out of the examination hall, he realizes that "z=0" was a blunder .
Then it was all Mishal , who narrated the story to everyone he can and made fun of Arshad.

But there are always conspiracy theories regarding anything.
The conspiracy theory says that this incident never happened (like moon hoax).
Some say it happened but Mishal was the one who said "Put z=0" not Arshad!
Anyhow it was one of the funniest incident ever narrated to me .

Have fun !
