MtheGM, I accept that some expressions such as "C'est moi," "It's me," "It's him," have become so common (pretty standard usage, in fact) that the grammatically correct forms may sound strange."   But if a person would never say "Give it to me" or "Me ate the pie," it makes no sense for that person to say "Give it to my husband and I" or "Me and my wife ate the pie."
I don't know why so many people seem to lose their inner sense of grammar when you stick a conjuction like "and" or "or" into the subject or object of a sentence.
