During the Mexican/American war, an intense long standoff 
occured 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?!".....
