'Sorry', said the Dentist. You are outside my specialty now. Yous should see a 'Laryngologist'!
By the time the unfortunate victim got to the Laryngologist, the tooth had worked its way down to the stomach. The Laryngologist examined the man. 'Sorry', said the doctor, You are outside my specialty now. You should see a 'Gastrologist'!
The Gastrologist X-rayed the pateitn. 'Sorry', said the doctor, the tooth has traveled further down into your lower intestines. You should see an 'Enterologist'!
The Enterologist took some X-rays. 'Sorry', the tooth is not there. It must have gone farther down. You should see a 'Proctologist'.
The patient is now on the Proctologists exmination table, in the proper elbow-knee position. The doctor inserted a Proctoscope and is looking through it.
'Good Heavens", man! You've got a tooth up there! You should see a 'Dentist'!
