Dick the Dawk, a scientist, who's much, much smarter than you, doesn't know what to say about this little ditty:
Speaking as a great admirer of Richard Dawkins (I always included The Selfish Gene on the syllabus of my ethics courses) I must admit that I'm kind of disappointed that he can't seem to figure out why this piss-take is so incredibly funny.
Best line in the rap: "Hey, if I was dyslexic, I'd even hate dog, too" - despite the grammatical error.
P.S.: for those unfamiliar, the chorus of Dick the Dawk's supporters is led by P. Z. Myers and includes, from left to right, at 2:40, Sam Harris, Eugenie Scott, Daniel Dennett, and Christopher Hitchens (with the I heart booze headband).
