Two blond girls were working for the city works department.
One would dig a hole, with the other following behind filling it in. They worked up one side of the street and down the other, furiously digging and filling in all day.
An onlooker, amazed at their hard work, couldn’t understand what they were up to and asked them about it.
The hole digger, wiping her face, sighed. “I suppose it looks odd, but we’re normally a three person team. But the girl who plants trees called in sick today.”
