Top brass from the Army, Navy and Marine Corps were arguing about who had the bravest troops. They decided to settle the dispute using an enlisted man from each branch.
The Army General called a private over and ordered him to climb to the top of the base flagpole while singing "The Caissons Go Rolling Along," then let go with both hands, and salute. The private quickly complied.
Next, the Admiral ordered a sailor to climb the pole, polish the brass knob at the top, sing "Anchors Aweigh," salute smartly and jump off. The sailor did as he was told and landed on the concrete below.
Finally, the marine was told to do exactly as the army and navy men had done, but in full battle gear, pack filled with bricks, loaded weapon carried high. He took one look at the Marine General and said, "You're out of your mind, sir!"
The marine commander turned to the others. "Now THAT'S guts!"
