Peace, aaarrgghhh! I am humming "Sitting at the dock..." and whistling too now! See what you've done!

I heard about the "bad luck" connotations with whistling too, Betsy, in Mediterranean countries. In some places they say you shouldn't whistle when walking past a cemetery. Don't know the origins though.

Liz, if you have Handel or Vivaldi at work to hum along with, you work in a higher class environment than most! Perhaps I should visit you and we can set up harmonies to annoy the little shit even more.

I love to hear people's impromptu humming. My wife and my daughter often hum at home as they're doing things, and it always cheers me up - it means they are in a good mood, I suppose.
