If you type in Google "Number of Horn on a Unicorn" Google Calculator tells you = 1 http://www.google.com/search?q=number+of+horns+on+a+unicorn&btnG=Google+Search
That IS rather sweet - it doesn't do it for all other 'number of' questions - I tried "number of legs on a dog" and "number of fingers on a hand" and got just the regular page of links, it seems only unicorns have this special ability
