BLONDE JOKE
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!
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 one who plants the trees called in sick."
