Glad you liked the lesson nik

But for a real laugh,imagine the comotion on deck,while the bloke is taking a dump over the side and an unexpected fighter plane (from an aircraft carrier who has been tracking them just out of range) screams down on top of them.He has 2 options.He either stays and finishes his dump while getting his ass cheeks riddled with lead,or he leaps from his 'seat' with his britches still beside his ankles and god knows what hanging from his back end while clambering down the hatch as fast as he can...mind the poor sod's head below :rotfl:
All this from a serious mature discussion about the food supplies of your typical UBoat
