A blonde who had been unemployed for several months got a job with Public Works. She was to paint lines down the center of a rural road. The supervisor told her that she was on probation and that she must stay at or above the set average of 2 miles per day to remain employed.

The blonde agreed to the conditions and started right away. The supervisor, checking up at the end of the day, found that the blonde had completed 4 miles on her first day, double the average! "Great," he told her, "I think you're really going to work out."

The next day, however, he was disappointed to find that the blonde only accomplished 2 miles. The supervisor thought, "Well, she's still at the average, and I don't want to discourage her. I'll just keep quiet."

On the third day, the blonde only did one mile and the boss thought, "I need to talk to her before this gets any worse." The boss pulled the new employee in and said, "You were doing so great. The first day you did 4 miles, the second day 2 miles, but yesterday you only did one mile. Why? Is there a problem? An injury, equipment failure? What's keeping you from meeting the 2-mile minimum?"

The blonde replied, "Well, each day I keep getting farther and farther away from the bucket."
