I was an Accident Investigator specialising in motor cycle accidents, and frequently appeared in Court as an Expert Witness. On one occasion a witness claimed a motorcyclist was out of control because he was "leaning right over" on a corner. Another time I had to explain to a Court that it was necessary (for a solo motorcyclist) to put his/her feet down when stationary! It transpired that neither the Judge nor the witness had ever ridden a bike, let alone a motorbike! On a different note in response to a question "How did you get to the site?" a witness, an elderly woman, answered "By Shanks's Pony" where upon a young Barrister leapt to her feet and demanded "M'Lud this is the first mention of a pony, I must take further advice from my Principal". Fortunately the Judge could advise the meaning of Shank's Pony to "Jane Nice But Dim".
