Lempi took a job with Odovero Construction to paint lines on M28. The first day he painted ten miles. The boss was very impressed.

The second day he painted two miles. The boss was a little disappointed. The third day he only painted 500 feet.

The boss sat him down and said," Lempi, how come you paint ten miles the first day, two miles the next day, but only 500 feet today?".

Lempi replied, "Well boss, each day I get farther and farther away from the paint can".
