"Dentist joke" joke

A dental surgery had been having an unusually busy day, and
ran out of local anaesthetic just before the last extraction
for the day was to be performed.
Keen to ensure that a far more painless extraction from the
patient's wallet would not be hindered, the dentist gave the
nurse a very large needle.
He instructed her to jab it firmly into the patient in the end
opposite to that from which the tooth was to be extracted,
when the signal was given.
It all happened in an instant. The patient and pliers were
in place. The signal was given, the needle driven well
home, and with a quick tug out came the tooth.
The dentist said, "Hurt much?"
The patient hesitated,
"Didn't even feel it come out... tell you what, though, the roots
were sure in deep!"
