A road crew supervisor hired a nice-looking blonde woman to assist with
painting the yellow line down the middle of the road. He was skeptical about
hiring her, but she appeared enthusiastic and told him that she really needed
the job. He explained to her that her work day would be to complete 2 miles
of line on her road, and he set her up with her brushes and paint and got
her started

After the first day, he was pleased to find that she did an excellent job
and was able to paint 4 miles of road in her 8 hour shift. He told her that
she did an excellent job and how pleased he was with her progress.

On the second day, she completed painting 2 miles of road. Her supervisor
was surprised that on day one she had completed twice as much work, but did
not say anything, as 2 miles of road was the amount that the job required
anyway. He decided to just accept it, and to look forward to the next day when
he was sure she would pick up her speed again.

On day 3 he was shocked to learn that in her 8 hour shift, she only
completed painting 1 mile of road. He called her into his office and asked her what
was the problem, "On your first day, you completed 4 miles of road, on your
second day, 2 miles of road, and now on day 3, you were only able to
complete 1 mile of road." "Can I ask you, what is the problem?"

"Well, she replied, I keep getting farther and farther from the paint can."
