Next time you use a pair of rubber gloves, you're going to smile when you think of this story:
A dentist noticed that his next patient, a little old lady, was quite nervous, so he decided to tell her a little joke as he put on his gloves.
'Do you know how they make these gloves?' he asked.
...
'No, I don't,' she replied.
'Well,' he spoofed, 'there's a Factory in Peking, China with a big tank of latex, and 500 workers of all hand sizes walk up to the tank, dip their hands in the latex, let them dry, and then peel off the gloves and throw them into boxes of the right size.'
She didn't crack a smile.
'Oh, well. I tried,' he thought.
But a few minutes later, during a delicate portion of the procedure, the patient burst out laughing.
'What's so funny?' he asked.
'I was just envisioning how condoms are made!'
