There is a factory in Northern Minnesota which makes
 the Tickle Me Elmo toys. The toy laughs when you
 tickle it under the arms. Well, Lena is hired at The
 Tickle Me Elmo factory and she reports for her first
 day promptly at 8:00 AM. The next day at 8:45 AM
 there is a knock at the Personnel Manager's door.
 The Foreman throws open the door and begins to rant
 about the new employee. He complains that she is
 incredibly slow and the whole line is backing up,
 putting the entire production line behind schedule.
 
The Personnel Manager decides he should see this for
 himself, so the 2 men march down to the factory
 floor.  When they get there the line is so backed up
 that there are Tickle Me Elmo's all over the factory
 floor and they're really beginning to pile up. At
 the end of the line stands Lena surrounded by
 mountains of Tickle Me Elmo's. She has a roll of
 plush red
 fabric and a huge bag of small marbles. The 2 men
 watch in amazement as she cuts a little piece of
 fabric, wraps it around two marbles and begins to
 carefully sew the little package between Elmo's
 legs. The Personnel Manager bursts into laughter.
 After several minutes of hysterics he pulls himself
 together and approaches Lena.
 "I'm sorry," he says to her, barely able to keep a
 straight face, "but I think you misunderstood the
 instructions I gave you yesterday...Your job is to
 give Elmo two test tickles."

Oldie but still made me chuckle. I think I may have hired Lena last week...
