During the Mexican/American war, an intense long standoff
occurred along the front. For days and days neither side made
any advances. Finally, an American general had a bright idea.

He aimed his rifle to the Mexican trenches and yelled "Hey
Juan!".....A soldier jumped up and replied "What?" The general
shot him dead. This continued for three days.

A Mexican general decided that two could play this game and
decided to try it out. He called out "Hey John!!"

An American replied "John isn't here......is that you Juan?" The
Mexican general stood up, "Yeah?!".....
