Two blond 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 understand
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."
