World War 3 and Mexico
Two lone soldiers are guarding the trenchline from enemy planes in World War Three.
After many minutes of waiting, one plane is seen flying above.
“What kind of plane is that, Sergeant?” asked the private.
“That’s a German plane. Shoot it down!” and both of them fired at it until it went down.
A few minutes later, another plane was seen flying by. The private asked what kind of plane that was.
“That’s an American plane. Shoot it down!” and they fired at it until it went down.
Yet again, another plane was seen flying by.
“What kind of plane is that?” asked the private.
“That’s a Mexican airplane. Don’t shoot it!”
“Don’t shoot it? Why?”
“Don’t worry, it’ll go down on it’s own.”
