You know how people call girls with blonde hair 'dumb blondes'? And how there are jokes about people like brunettes and redheads and blondes, and the blondes are always saying something dumb? Usually now, when you act sort of off or dumb, people say you are having a " blonde moment." which means you are having a dumb moment.

Not every one thinks blonds are dumb. the reason however for the dumb blond jokes stem from the the dumb blonds they used to portray in the old movies.
Brunettes are often considered to be more uptight than their blonde counterparts. Often associated with being smarter and more successful , they are also depicted as being less attractive than blondes.
