HUMOUR ---TRI AS YOU MIGHT

Three engineers are in a car rushing at breakneck speed down a country road,when suddenly the driver realises he has no brakes.He slams his foot on the pedal but it's no use;the car can't be stopped.
The car hurtles around a blind corner,bursts through a fence,rushes headlong through a herd of cows and careers to a dramatic stop in a well placed haystack.
The three engineers,unhurt but shaken,crawl from the car to investigate what went wrong.
The first,a mechnical engineer,looks underbeath and sees that the brake line is burst.He says they ought to repair it and continue on their way.
At this,the second,a system engineer,sighs and says that the safest bet would be a full diagnostic check of the whole vehicle."It's the only way."
The third,a software engineer,laughs at both of them and says "Don't be silly,it is probably nothing to worry about.Let's go back in,restart the car and see if it happens again.
