One did !

Absolutely ! The "quo vadis" version occurred to me after I'd posted my alternate correction.

@Anonymous: "Where doth thou goest ?" is completely off key.
It should be, were one to express oneself in such antiquated verbiage,
"Where dost thou go ?"

@semiotek: the "it is I", "It's me" debate is a question of usage and context. The use in French of stressed personal pronoun "moi" in this construction ( "C'est moi" ) may well be at the origin of the "me" in English in this phrase.

I, for one, find nothing wrong with correct grammar. While "who" is often substituted for "whom" , it doesn't cost anything to say or write the correct form.

I remember seeing a t-shirt imprinted with the quote
"It's not who you know,
it's whom you know."

Sums it up nicely for me !
