I heard of an Army Officer who was transferred to a new camp and visiting the Officers Mess noticed that a deep scratch mark had been made at about 7" from the edge of the highly polished bar .Upon enquiries, about what appeared to be an act of vandalism, he was informed that it was to indicate the biggest barrel length amongst the officers weapons. Looking carefully at the mark, the newly arrived officer said "Do you know I reckon I could better that". Whereupon the Barman said....."From this side of the bar Sir".
