There's got to be a way we could work a sheep dog into this, too.

A really smart sheep dog that can recognize when you tag a sheep with
a water-soluble paint or something, and herd it over into a corner so
you don't count it twice and it's out of the way.  Even if he missed
one, you'd see the paint, too.  Then we can use the regular
subtraction routine.
