Looking for sample 16 X 16 icons

I need to make a demo program for a meeting, and need 4 16 X 16 icons.  But any search for icons brings up a single image with hundreds of icons.  I would need to cut out a 16 X 16 area, and I do not have that kind of time.

Any place where I can find free icon files which I can simply download and insert in my program?

Thanks!
