Here's one i heard a long time ago.

A manager, hardware engineer and software engineer are in a car travelling across a twisty mountain road. Suddenly the car inexplicably swerves from side to side only stopping just before the car plunges into the ravine.

Manager:
"Let's call out the recovery services and get it to a workshop".

Hardware engineer:
"Let's see if we if we can fix it ourselves".

Software engineer:
"Let's drive further down the road and see if it happens again".
