I totally support the idea of himself calling himself a doctor. It's great humor. A sign of intelligence is a good sense of humor. I can see the joke has been lost on you.
Kent Hovind says (in his statement above) that he doesn't care whether he is addressed as "Mr." or "hey you" by the scoffers. In fact, his Ph.D. is very precious to him or he would not be listed as "Dr. Kent Hovind" in the Pensacola, FL, phone book (it is very unusual for a person with a Ph.D., even a real one, to do this). One has only to look at his itinerary to substantiate my claim that being called "Doctor" is very important to him.How is anyone looking up the phone book supposed to "get the joke"? They have no way of knowing at thar time that Hovind's title is a facade.
