I have encountered this one in multiple places and find it amusing. Most recently in this video at 1:52. In trying to be "politically correct" the meaning of a name is changed totally. When describing the engine crew, the account here altered the name of the fireman to "Fire Fighter". The fireman did not fight any fires. His duties involved tending the fire in the boiler, adding fuel and water to the boiler to maintain the desired steam pressure. A better name would have been fire "maintainer" or maybe something else. He was trying to keep the fire going, not put it out.
