"Very Modest Lady" joke

A very modest lady applied for a job at the factory where they made
the Tickle-Me-Elmo dolls".
It was Friday and almost quitting time and hurriedly the boss told her
to report for work on Monday and then explained she would be stationed
on the assembly line just before the dolls were packed into boxes.
Monday they started up the line and within twenty minutes had to shut
it down because one worker couldn't keep up. The boss went down the
line to find the problem.
The new employee was very busy trying to do her part but she had a
bunch of dolls waiting for her. Closer examination showed she was sewing
little cloth bags containing two walnuts in the appropriate place on
the dolls.
When the boss could control his laughter he said, "Lady, I said to
give each doll two test-tickles".
