One would dig a hole and the other would follow behind him and fill the hole in.
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"
