John Kerry is an alien

It came to me as a revelation. How come Kerry was so familiar to me. And then I understood.

Kerry is actually Dick in Third Rock from the Sun. In order to blend in, he assumed the human form of actor John Lithgow utilising a bald wig. Since the show finished its run he thought with his enormous intelligence that he should run for President. The Big Giant Head, however, is considering calling him back now his cover is blown.

Can Tom, Dick, Harry and Sally persuade BGH otherwise ?
