Ever need one of these?  Do you know what to ask for?  I have known the correct terminology for many years, yet I can never remember it when I need to ask for one so I have to resort to "I need four large thin washers with a small hole."  Then the hardware person says, "Sure.  We have a large assortment of fender washers on aisle three."

How hard can it be to remember "fender washer"?

By writing this the author hopes to amuse you, but more importantly he hopes to be able to ask for the item by name the next time he needs one.
