They worked furiously all day without rest, one guy digging a hole, the
other guy filling it in again.
An onlooker was amazed at their hard work, but couldn't understand what
they were doing. So he asked the hole-digger, "I appreciate the effort
you are putting into your work, but what's the story? You dig a hole and
your partner follows behind and fills it up again?"
The hole digger wiped his brow and sighed, "Well, normally we are a
three-man team, but the guy who plants the trees is sick today."
