A new employee is hired at the Tickle Me Elmo (a cuddly toy which laughs when tickled) factory. The Personnel Manager explains her duties and tells her to report to work promptly at 8.00am.
The next day at 8.45am there is a knock at the Personnel Manager's door. The assembly line foreman comes in and starts ranting about this new employee. He says she is incredibly slow and the whole line is backing up. The foreman takes the Personnel Manager down to the factory floor to show him the problem.
Sure enough, Elmos are backed up all over the place. At the end of the line is the new employee. She has a roll of material used for the Elmos and a big bag of marbles. They both watch as she cuts a little piece of fabric, wraps it around two marbles and starts sewing the little package between Elmo's legs.
The Personnel Manager starts laughing hysterically. After several minutes he pulls himself together, walks over to the woman and says "I am sorry, I guess you misunderstood me yesterday, I said, your job is to give Elmo "two test tickles".
