Dentist's office
 

A man and his wife entered a dentist's office.
The wife said, "I want a tooth pulled. I don't want gas or Novocain because I'm in a terrible hurry. Just pull the tooth as quickly as possible."
"You're a brave woman," said the dentist. "Now, show me which tooth it is."
The wife turns to her husband and says: "Open your mouth and show the dentist which tooth it is, dear."
