2 blondes, employed by the city street department, were working on the tree lawn- the grassy area between the street and the sidewalk. One blond would dig a hole, and the other would fill it in. They had covered about 3 blocks, and a local business owner had been watching for a half hour or so, when curiosity got the best of him. He walked out to the two blondes and asked why they were doing what they were doing, 1 blond digging a hole and the other filling the hole in. The first blond replied "We usually have another blond working with us, but she called in sick today. She's the one who puts the tree in the hole."
