Again, more from the collected wit and witticisms of Mr. John Navas.
Distilled from ba.internet postings:

|navas|  I doubt that anything I could say would improve my "credibility"

|higdon| Well, at least I didn't say it.        

|navas|  In fact you've made that clear, and so it's not terribly surprising 
         to find you accepting that statement.  But if you think about it for 
         more than a microsecond, you should be able to see that it's a 
         reflection on you, not me. ;-)  

|higdon| Not in the slightest. If you COULD say anything that would improve 
         your credibility, I'm sure you WOULD. But since you don't, I have to 
         assume that you can't.
      
	 It is not in my listening; it is in your speaking.
     
|navas|  Uh huh.  Fallacious, and very childish.

|higdon| Ah, your favorite meaningless insult. Really good comeback.
