General McKenzie was in charge of the Navy, and he was visiting his colleague General Marshall, who was in charge of the Army. McKenzie arrives at the military camp and is greeted by Marshall. They both walk around the place, and McKensie asks: "So how are your men?"
"Very well trained, Gral. McKenzie."
"I hope so. You see, my men over at the Navy are so well trained, you could see they4re the bravest men all over the country." "Well, my men are very brave, too."
"I4d like to see that."
So Marshall calls private Cooper and says: "Private Cooper! I want you to stop that tank coming here with your body!"
"Are you fucking crazy? It4d kill me, you asshole! I4m out of here!" As private Cooper ran away, Marshall turned to a bewildered McKenzie and said:
"You see? You have to be pretty damn brave to talk like that to a general."
