When Phil's power mower broke down, his wife Kristi kept dropping hints about getting it fixed before the grass got too tall, but the message wasn't sinking in, and Phil kept putting off the repairs. Finally, she thought of a clever way to make her point. When Phil arrived at home one day, he found her sitting in the grass, clipping it by hand with a tiny pair of sewing scissors. He watched silently for a few minutes, then went into the house. Coming back in a few minutes, he handed her a toothbrush.
"When you finish cutting the grass, you might as well sweep the sidewalks."
