That depends on whether you follow the American or British punctuation system. In the American system, assuming it isn't an exception, of which there are numerous (for example in Government manuscripts, where the comma is not part of an official quotation or instruction), the comma or full stop (period) would go before the comma. In the British system position is determined by context; he was using a quotation so he would not put the comma inside unless it were part of the quotation.
And if you want to be pedantic, it shouldn't have gone before the 'quote'. That would have made it ",exclamation mark". It should have gone, in the American system, before the quotation mark. See http://englishplus.com/grammar/00000244.htm. And before you quote it, I don't care what dictionary.com says, it's wrong in this instance.
