Don't shoot the blogger, this was told by a German person to an American Person!
In World War 1 there was trench warfare, and neither the Americans nor the Germans could get the upper hand.
They were reaching a stalemate.
Until one day an American came up with a plan that would win them the war.
This private explains his plan to his trench mates, and they figured 'why not?' its not like they have any better ideas.
The next day an American soldier calls out, "Hans!?"
A German pops up and shouts back, "Ja?!"
Boom The German is shot dead.
The next day another shout from the Americans, "Hans?!"
"Ja?!" Shot dead.
This process continues over the next couple of days.
Germans are losing large numbers, and are now finally catching on. The
Germans have an emergency meeting, Maybe they can come back from the
heavy losses using the same tactics as the Americans.
So, a German asks "What ist a Popular Amerikan Name?" "John!" replied another.
The next day the Germans decided to execute their plan.
A German shouts, "John!?"
An American calls back, "Is that you Hans?!"
And that is how the Americans won WWI
