A 17 year-old Antartian boy was hired to paint a white line down the middle of the highway. On the first day, he got off to a good start and he painted a white line 7 miles long. The next day, however, he painted a line only 4 miles long. On the third day, he was down to less than a mile. Finally, his friend Max asked him why he was doing less each day. The boy replied, "I guess it takes me longer and longer to get back to the bucket each day."
