Squeaky-clean grass
Here we have a study in wasting your time. I’m really not sure what this guy thought he was doing. Perhaps he spilled something on his lawn, and the appliance that immediately came to mind was the vacuum. He’s even pulled out an extension cord to make sure it reaches.
The thing that worries me is how he’ll decide he is done? What are the success criteria? The elimination of all dirt? He might be a while. His wife is probably taking this photo and being torn between laughing at his stupidity and despairing that she’s married to the guy vacuuming his lawn.
