A women desperately looking for work goes into a toy factory.
The Personnel Manager goes over her resume and explains to her that he regrets he has nothing worthy of her. The woman answers that she really needs work and will take almost anything. The Personnel Manager hems and haws and finally says he does have a low skill job on the Tickle-Me-Elmo line and nothing else. The woman happily accepts.. He takes her down to the line and explains her duties and that she should come in at 8am the next day.
The next day at 8:45 there's a knock at the Personnel Manager's door. The Tickle-Me-Elmo line manager comes in and starts ranting about the woman just hired. After screaming for 15 minutes about how badly backed up the assembly line is, the Personnel Manager suggested he be shown the problem.
Together they head down to the line and sure enough Elmos are backed up from here to kingdom come. Right at the end of the line is the woman just hired. She has pulled over a roll of the material used for the Elmos and has a big bag of marbles. They both watch as she cuts a little piece of fabric and takes 2 marbles and starts sewing them between Elmo's legs.
The Personnel Manager starts to kill himself laughing and finally after 20 minutes of rolling around, he pulls himself together and walks over to the new employee and says...
"I'm sorry, I guess you misunderstood me yesterday.
What I wanted you to do was give Elmo two test tickles."
