To tell the truth for a time I was having second thoughts and feeling a little guilty thinking that maybe I was being too hard on you; I was thinking that you couldn't passably be as dumb as you seemed to be and so maybe I was just misunderstanding what you were trying to say. But you're above statement is as clear as it is imbecilic and so I must conclude that my first impression was correct, you really are too dumb to walk and chew gum at the same time.
