Birthday suit!

It was 5 o'clock in the morning at the U.S. Marine boot camp, well
below freezing,

And the soldiers were asleep in their barracks. The drill sergeant
walked in and bellowed,

"This is a birthday suit inspection! I wanna see you all formed up
outside and butt naked now!"

The soldiers quickly jumped out of bed, naked and shivering, and ran
outside to form up in their three ranks.

The sergeant walked out and yelled, "Close up the ranks and conserve
your body heat!" The soldiers complied and moved closer together.

The captain appeared with his swagger stick. He walked up to the
first soldier and whacked him right across the chest. " Did that
hurt?" he yelled. "No, Sir! " "Why not?" "Because I'm a U.S. Marine,
Sir!"

The captain then walked up to the next soldier and whacked him right
across the chest. " Did that hurt?" he yelled. "No, Sir!" "Why
not?" "Because I'm a U.S. Marine, Sir!"

The captain was rather impressed with the toughness of the soldiers;
so he walked up to a third soldier.

The captain noticed that the soldier had an enormous erection, so
naturally he gave his target a huge whack with the swagger stick. "
Did that hurt?" he yelled. "No, Sir! "

"Why not?" "Because it belongs to the guy behind me, Sir! "
