Heres the ice fishing story, and I apologize that is was not Minnesota like I once thought:
http://www.traagstad.com/humor/isfiske.htmlAnd here is one of my favorites:
Employees in a medium-sized warehouse in west Texas noticed the smell
of a gas leak. Sensibly, management evacuated the building,
extinguishing all potential sources of ignition lights, power, etc.
After the building had been evacuated, two technicians from the gas
company were dispatched. Upon entering the building, they found they had
difficulty navigating in the dark. To their frustration, none of the
lights worked (you can see what's coming, can't you?). Witnesses later
described the sight of one of the technicians reaching into his pocket
and retrieving an object that resembled a cigarette lighter. Upon
operation of the lighter-like object, the gas in the warehouse exploded,
sending pieces of it up to three miles away. Nothing was found of the
technicians, but the lighter was virtually untouched by the explosion.
The technician suspected of causing the blast had never been thought of
as 'bright' by his peers.
