Will He Be A Menace?

While I was out and about today a woman and her perhaps 4 year old son sat near me on the bus.  His name was Dennis.  An unusual name for a little boy these days, and thinking about it I suspect it's an unusual name for anybody under 40 or so.  It's probably not as archaic a name, if you will, as a name like Eunice or Margery, but it might be getting there.
