In America, commas go inside the quotation mark (except as stated below, when the question is not part of the quote, it goes outside the quotation mark).
However, in the UK, commas, question marks, etc. all go outside the quotation marks. As always, you need to know your audience!

I agree with Mike, I can't think of any instances where a comma outside of quotation marks would be appropriate.
