The army had to fire three of their generals..

They decided that a monetary compensation would be fitting, so they lined the three generals up and said:

"You will be paid a thousand dollars for each centimeter of distance you create from one body part to another"

The first general stretched his arms as far from each other as he possibly could, and said
"Measure the distance from the fingertips on my left hand, to the fingertips on my right hand." they paid the general and went on to the next.

The second general stretched his arms as far above his head as possible and said
"Measure the distance from the tip of my fingers to the tip of my toes" he was paid, and left with even more money than the first general.

They got to the final general, who promptly said
"I want you to measure the distance from my left nut to my right nut"
The soldier with the measuring tape didn't understand what was happening but did as he was told. A few moments later the confused soldier said "Sir, i don't understand. I can only see your right nut"

The general said with a big smile on his face:
"I know, i lost my left nut in 'nam"
