I like that first one. Very funny!

The young 2nd Lieutenant approached the crusty old Chief Master Sgt. and asked him about the origin of officers' insignias.
"Well, Lieutenant, it's history and tradition. First, we give you a gold bar representing that you're valuable but malleable. The silver bar of a Lieutenant represents more value but less malleable.
When you make Captain, you're twice as valuable so we give you two silver bars.
As a Colonel, you soar over the military masses, hence the eagle.
As a General, you're obviously a star. That answer your question?"
"Yes, but...what about Majors and Lieutenant Colonels?"
"Now that goes waaaaaay back in history. Back to the Garden of Eden even.
You see, we've always put leaves on our pricks!"

@1LT Brian Brantley Not much of a joke, just a fact.

Crabs over castles.
