Leg looks for body

Has anybody lost his leg? I wonder what happened with the owner of this orthopaedic leg. Maybe he was in a hurry and he had to leave quickly, even without his leg. Or maybe he was at home, having lunch, and he left his leg just to keep the place. Or maybe he thought that the leg could beg properly without the rest of the body. Or maybe he was a street seller of second hand junk and the orthopaedic leg was part of his stuff. Unfortunately, I couldn’t wait to solve the mystery.
