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 two 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 four 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 two miles.
The supervisor thought, "Well she's still at the average 
and I don't want to discourage her, so I'll just keep quiet."
The third day however 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 four 
miles, the second day two miles, but yesterday you only did one mile. Why? Is 
there a problem? An injury, equipment failure? What's keeping you from meeting 
the two-mile minimum?"
The blonde replied "Well, each day I keep getting farther and farther away 
from the bucket."
