Blondes 

First of all, all these rumors about blondes being "thick" are actually true. There is a tiny cell in the blondes hair called Algiatarus. Algiatarus is a small bacteria that brakes down cells. though blondes might learn all of this smart knowlege, the Algiatarus brakes down the memory cells in the "blondes" brain. A famous scientist named Richard Montel, discovered this. Though at first nooene believed his theory. it was only after he died that his "brunette" daughter Anja Montel proved her fathers theory to the public. This was in the late 1890's (1894). but Richard Died 3 Years before his beloved daughter proved his theory.Please wait for further information on this subject as i will be updating it.
