Not really a joke … just a tiny bit of math fun.

142857 is a cyclic number – its digits always appear in the same order but will rotate around when multiplied by any number from 1 to 6:

142857 x 1 = 142857
142857 x 2 = 285714
142857 x 3 = 428571
142857 x 4 = 571428
142857 x 5 = 714285
142857 x 6 = 857142

Pretty cool, huh? Now multiply 142857 by 7.

A woman went to her doctor’s office. She was seen by one of the new doctors, but after about 4 minutes in the examination room, she burst out screaming and ran down the hall.

An older doctor stopped her and asked what the problem was, and she explained. He had her sit down and relax in another room.

The older doctor marched back to the first and demanded, “What’s the matter with you? Mrs. Terry is 63 years old, she has four grown children and seven grandchildren, and you told her she was pregnant?”

The new doctor smiled smugly as he continued to write on his clipboard.

“Cured her hiccups though, didn’t it?”
