Why is it better for manhole covers to be round rather than square?

The reason that manhole covers are round, and not square, is because a square cover could, when placed at the right angle, fall through the square hole in the ground. A circle, however, is the same diameter no matter where you measure it, and it cannot fir through a hole the same size and shape, no matter how hard anyone tried.
