Road Painting

One day this blonde got hired for a job, painting lines on the road. The first day on the job she painted 20 miles of lines, the second day she painted only 15 miles, the next day 10 miles and then the next only 5 miles. That day her boss asked her "How can you do 20 miles of lines one day then 3 days later only do 5 miles of lines?" 

"It's one long walk back to that paint can!" she replies.
