From the illustrious Dr Boli (links added, for extra enjoyment):
Now that racism is dead and the darkies have everything they want, is it not high time to end the senseless discrimination against stupid people? Statistics say that 50% of the population is of below-average intelligence, but I believe the true figure is much larger. I myself have been proudly stupid for my entire adult life. I was a stupid child as well, and I came from a long line of stupid ancestors. Indeed, family tradition says that our ancestry goes back further than any other family’s, and I firmly believe every unexamined tradition I hear. The secret of my success has been, in one word, credulity. If I could remember what this letter was about, I should have ended it with a zinger that would make my opponents feel awfully silly.
