No wonder why everyone laughs at the expense of blondes and most jokes are about them. We all love jokes because we evoke amusement , but like most about blondes are too much. But I do not think the influence that they are blonde and that everyone jokes about them . The blond is their hair color and think it is a coincidence of all these things happening to them. All this could happens and a brunette for example. Probably coincidence that everyone made fun of blondes is because hair color does not differentiate between people , but it is the mind that differentiates us in society.
