An Australian Combat Field Engineer Sergeant and a U.S Marine were on exchange duty and were sharing the latrines.
The Aussie Sergeant finished first and walked out without washing his hands. The U.S Marine watched in disgust, finished his squirt, washed his hands and walked up to the Aussie Sergeant and said. " In the U.S Marine Corps we were taught to wash our hands after a leak".
The rather large Aussie Sergeant replied, "In the Australian Army mate, we were taught not to piss on our hands...!"
