Sounds Like a Dental Procedure

Speaking of which... I was recently in a dental chair, and the Dentist is all up in my mouth, going from tooth to tooth saying to his assistant, "Ext 16, ext 12, ext 8," etc. I was trying to figure out what he meant, then my eyes almost bulged out their sockets when I realized he means EXTRACTION!!!! Wake me up, get me out of this chair!
