Two blonde girls were working for the city public works
department. One would dig a hole and the other would
follow behind her and fill the hole in.
They worked up one side of the street, then down the other,
then moved on to the next street, working furiously all day
without rest, one girl digging a hole, the other girl
filling it in again.
An onlooker was amazed at their hard work, but couldn't under-
stand what they were doing.
So he asked the hole digger, "I'm impressed by the effort you
two are putting into your work, but I don't get it -- why do
you dig a hole, only to have your partner follow behind and
fill it up again?"
The hole digger wiped her brow and sighed, "Well, I suppose
it probably looks odd because we're normally a three-person
team. But today the girl who plants the trees called in sick."
