If the doc is going to keep ncreasing needle size as punishment one day the needle isn't going to fit through the door.
Also I do believe the plural of "small fry" is just "small fry" officially and "small fries" unofficially. The latter is used by people who who incorrectly think of the food , but has become common enough that it's somewhat accepted, but officially fry refers to a group of newborn fish and already is plural.
