Back when I played D&D, we had a special place for that most silly sounding weapon: the Bohemian Earspoon.
My wife recently related to me that an earspoon is a tool once used for cleaning the ear, and putting the wax so acquired to other industrious uses (Eeeewww!)
So the suggestion is that a large polearm be used for cleaning the ear is kind of funny (at least if it's not your ear!), and was obviously intended to be a joke all along.
Now it get it! :-)
