Don't Get Blown Away

One day, two guys were standing inside the food court building at a local theme park.  They were looking out the window and were discussing how it was an extremely windy day.  The area's custodian, the one who had the job of sweeping up debris, was a very small woman who did not weigh much, and they could see she was having a rough time trying not to be blown away.

When it came time for her to take her break, she went inside the building.  Her clothes were all disheveled, and she had leaves sticking out of her hair.  One of the men decided to joke with the lady, telling her that she should put heavy rocks in the bottom of her shoes when she planned to go back outside to work.

The lady looked up at him and smiled.  "Oh," she said, "I see.  You mean, now I weigh me down to sweep?"
