Dear Keiva: One fox does not a pack make.
Dear dr. bill: We're agreed that your post titled "Packs of Dogs" was erroneous in the title's first word as well as in its last. But Flirt took great umbrage at the latter.
BTW, no number of foxes constitutes a "pack"; the venereal term is, I believe, "a skulk of foxes".
BTW#2: As a matter of grammar, should my last sentence have said "constitute" or "constitutes"?
