A trip to the dentist:

A dentist noticed that his next patient, a little old lady, was very
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 building in Canada with a big tank of
latex, and workers of all hand sizes walk up to the tank,
dip their hands in, let them dry, then peel off the gloves
and throw them into boxes of the right size'


She didn't even crack a smile!



'Oh, well. I tried' he thought.



Five minutes later,
during a delicate portion of the procedure,
she burst out laughing!


'What's so funny?' he asked.


'I was just envisioning how condoms are made!'
