Cover art for Mrs. O. lyrics by Dresden Dolls, The

Mrs. O is obviously a schoolteacher, one who taught that the holocaust never happened. The interesting thing about the song is that it ironically salutes Mrs. O, wondering "will you leave us hanging now that you are old?" Don't we wish we could be fooled so easily now that we see how the world really is?

I think the "yes, Virginia" line ties it together well. Most of us seem to grudgingly agree that it's okay to tell children appealing lies, making the world seem a better place. But where does it end?

I thought that Mrs. O was referring to Virginia O'Hanlon, who as a child wrote to the Sun in 1897 to ask if there was a Santa Claus.

The response was, in part, "Yes, Virginia, there is a Santa Claus".
