Dr. W. H. Thomson, in his book on "What is Physical Life," says that, "once, while talking to a roomful of the naturally bright people of a town in Mount Hermon about the achievements of Western civilization, I happened to tell a toothless old man present that in our country we had skilled persons who could make for him an entirely new set of teeth. Glancing round the room, I noticed some listeners stroking their beards in a fashion which I knew meant that I was telling a preposterous yarn. Fortunately I had with me an elderly Scotch friend who had a set of false teeth, and on explaining the situation to him, he forthwith opened his mouth and pulled the whole set out. The Arabs jumped to their feet in fright, not sure but he might start to unscrew his head next, for had any of their venerated ancestors ever seen such an uncanny performance with teeth? They afterward said that never would they have believed this if they had not seen it."
