Work, work, work
Two men from the city public works department were working their way down the street. One dug a hole in the ground between the sidewalk and the street.
The other followed close behind filling shoveling the dirt back into the holes.
After watching this for over an hour, a neighborhood resident finally asked them what they were doing.
“I’m impressed by the effort you two are putting in, but I don’t get it—why does one of you dig a hole and the other fill it in almost immediately?
“Well, we’re normally a three-man team, but the guy who plants trees called in sick today.”
