Monty Python Guide to Shoulder Lifts

First shalt thou take thine partner up to thine shoulder. Then shalt thou turn three times. No more. No less. Three shalt be the number of thine turns, and the number of the turns shall be three. Four shalt thou not count, nor either turneth thou two, excepting that thou then proceed to three turns. Five is right out. Once the number three, being the third turn, be reached, then slideth thou thine partner down thine back towardeth the floor.
