At the international dentist convention the dentists from Iraq were displaying their new extraction technique.
With this device you can remove teeth from a patients mouth by entering through the rectum and navigating through their digestive track to pull the tooth out.
A dentist in the audience asks “Why did you make this?”
The iraqi dentist “Because Iraqis never open their mouths”
(At the time Saddam was killing anyone for talking bad about him)
