A farmer sitting on his porch noticed a highway-department
truck pull over on the road's shoulder. A man got out, dug a
sizable hole in the ditch, and got back in the vehicle. A few
minutes later, the other occupant of the truck got out, filled up
the hole, tamped the dirt, and got back in the truck.

Then they drove forward on the shoulder about 50 yards and
repeated the process--digging, waiting, refilling. After a half-
dozen repetitions, the farmer sauntered over to them. "What
are you doin'?" he asked.

"We're on a highway beautification project," the driver said.
"And the guy who puts the tree in the hole is home sick
today."
