We'll begin with a box, and the plural is boxes, but the plural of ox becomes oxen, not oxes.
One fowl is a goose, but two are called geese, yet the plural of moose should never be meese. You may find a lone mouse or a nest full of mice, yet the plural of house is houses, not hice.

If Father is Pop, how come Mother's not Mop.???
