URBAN LEGEND: The DOG and the JEEP
http://darwinawards.com/legends/legends1999-09.html

A Michigan fellow buys himself a brand-new $30,000 Jeep Grand
Cherokee for Christmas.  He goes down to his favorite bar and
celebrates by tossing down a few too many brews with his buddies.
In one of those male-bonding rituals, five of them decide to take
his new vehicle for a test drive on a duck hunting expedition.
They load up the Jeep with the dog, the guns, the decoys, and the
beer, and head out to a nearby lake.

Now, it's the dead of winter, and of course the lake is frozen,
so they need to make a hole in the ice to create a natural
landing area for the ducks and decoys.  It is common practice in
Michigan to drive your vehicle out onto the frozen lake, and it
is also common (if slightly illegal) to make a hole in the ice
using dynamite.  Our fellows have nothing to worry about on that
score, because one member of the party works for a construction
team, and happens to have brought some dynamite along.  The stick
has a short 20-second fuse.

The group is ready for some action.  They're all set up.  Their
shotguns are loaded with duck pellets, and they have beer, warm
clothes and a hunting dog.  Still chugging down a seemingly
bottomless supply of six-packs, the group considers how to safely
dynamite a hole through the ice.  One of these rocket scientists
points out that the dynamite should explode at a location far
from where they are standing.  Another notes the risk of slipping
on the ice when running away from a burning fuse.  So they
eventually settle on a plan to light the fuse and throw the
dynamite out onto the ice.

There is a bit of contention over who has the best throwing arm,
and eventually the owner of the Jeep wins that honor.  Once that
question is settled, he walks about 20 feet further out onto the
ice and holds the stick of dynamite at the ready while one of his
companions lights the fuse with a Zippo.  As soon as he hears the
fuse sizzle, he hurls it across the ice at a great velocity and
runs in the other direction.

Unfortunately, a member of another species spots his master's arm
motions and comes to an instinctive decision.  Remember a couple
of paragraphs back when I mentioned the vehicle, the beer, the
guns and the dog? Yes, the dog: a trained Black Labrador, born
and bred for retrieving, especially things thrown by his
owner.  As soon as the stick leaves his hand, the dog sprints
across the ice, hell-bent on wrapping his jaws around the
enticing stick-shaped object.

Five frantic fellows immediately begin hollering at the dog,
trying to get him to stop chasing the dynamite.  Their cries fall
on deaf ears.  Before you know it, the retriever is headed back to
his owner, proudly carrying the stick of dynamite with the
burning 20-second fuse.  The group continues to yell and wave
their arms while the happy dog trots towards them.  In a desperate
act, its master grabs his shotgun and fires at his own dog.

The gun is loaded with duck shot, and confuses the dog more than
it hurts him.  Bewildered, he continues towards his master, who
shoots at man's best friend again.  Finally comprehending that his
owner has become insane, the dog runs for cover with his tail
between his legs.  And the nearest cover is right under the
brand-new Jeep Grand Cherokee.

Boom! The dog and the Jeep are blown to bits, and sink to the
bottom of the lake, leaving a large ice hole in their wake.  The
stranded men stand staring at the water with stupid looks on
their faces, and the owner of the Jeep is left to explain the
misadventure to his insurance company.  Needless to say, they
determined that sinking a vehicle in a lake by illegal use of
explosives is not covered under their policy, and the owner is
still making $400 monthly payments on his brand-new Jeep at the
bottom of the lake.

A boy returning home from his first day at school said to his mother, "Mom, what's sex?"

His mother, who believed in all the most modern educational theories, gave him a detailed explanation, covering all aspects of the tricky subject.

When she had finished, the boy produced an enrollment form which he had brought home from school and said, "Yes, but how am I going to get all that into this one little square?"

Allegedly, a Pan Am 727 flight waiting for start clearance in Munich overheard the following:
Lufthansa (in German): "Ground, what is our start clearance time?"
Ground (in English): "If you want an answer you must speak in English."
Lufthansa (in English): "I am a German, flying a German airplane, in Germany. Why must I speak English?"
Unknown voice from another plane (in a beautiful British accent): "Because you lost the bloody war."

Allegedly the German air controllers at Frankfurt Airport are renowned as a short-tempered lot. They, it is alleged, not only expect one to know one's gate parking location, but how to get there without any assistance from them. So it was with some amusement that we (a Pan Am 747) listened to the following exchange between Frankfurt ground control and a British Airways 747, call sign Speedbird 206.
Speedbird 206: "Frankfurt, Speedbird 206 clear of active runway."
Ground: "Speedbird 206. Taxi to gate Alpha One-Seven." The BA 747 pulled onto the main taxiway and slowed to a stop.
Ground: "Speedbird, do you not know where you are going?"
Speedbird 206: "Stand by, Ground, I'm looking up our gate location now."
Ground (with quite arrogant impatience): "Speedbird 206, have you not been to Frankfurt before?"
Speedbird 206 (coolly): "Yes, twice in 1944, but it was dark,... and I didn't land."
