Joke: Public Works-Fool joke

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."
