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

understand what they were doing. So he asked the hole digger,

'I'm impressed by the effort you two are putting in to 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.'
