A Trip to the Dentist

Nervous about going to the dentist, I first stopped at the bar to have a drink or two to calm my nerves. I arrived at the office and went back to the examination room as directed, and sat.

Then I thought - most dentists chairs go up and down, don't they? The one I was in went forwards and backwards. How unusual.

The dentist came in and said to me, "Sir, please get out of the filing cabinet."
