I was observing two men that were working for the public works department. One would dig a hole and the other would follow behind him and fill the hole in.
After a while I had to ask, "Why do you dig a hole, only to have your partner follow behind and fill it up again?"
The hole digger wiped his brow and sighed, "Well, I suppose it probably looks odd because we're normally a three-person team. But today the lad who plants the trees called in sick."
