During a training session at an artillery unit the sergeant-major was busy describing how the sophisticated aiming device of the artillery weapon system is used.

"As you all know, there are 180 degrees in a circle."

One of the soldiers put up his hand and said: "But there are 360 degrees in a circle, sergeant-major."

"You idiot," replied the sergeant-major, "I am obviously speaking about a small circle!"
He said: When I was a newly commissioned Lieutenant in the Army, I was assigned as a temporary assistant in an administrative office in a Military Intelligence unit.

One day, a long memo came around with a cover sheet instructing all assigned officers to read it and initial it as indication of their compliance. I figured it meant me too, so I read and initialed it.

But, a few days later, it came back addressed specifically to me. An attached note read, `You are not permanently assigned to this unit and are thus not an authorized signee. Please erase your initials and initial your erasure.`
