9. Toy Car
Practically every young boy in the western world has played with toy cars at one time or another, careening them underneath the dining table much to the annoyance of their mums and creating enormous blood-free pile-ups on the bedroom carpet. Some bright spark had a far different idea of how you should play with toy cars - it's not known how much fun they had before it got lodged inside them but presumably they were none too happy walking awkwardly to the hospital to ask the doctor to get their toy back for them.
