Since we're on the subject, saying "a French" sounds wrong to me (American native English speaker), even though the same construction is OK for other nationalities. (E.g. "a German" is OK.) You're better off with "a Frenchman"/"a Frenchwoman" or "a French person".

I love the total unrelated pieces of trivia you can find on the comments.

I know about the "Oxford comma" (I think that's how is called), as they taught me to never put a comma and a conjunction in a list of things and the two spaces after a sentence...

Yup, above it's a case of missing "Oxford comma"... ^__^;
