Remember why blondes are a favorite target of jokes

Although there is no evidence for it, apparently the first blondy jokes created in the 18th century thanks to the beautiful French courtesan Rosalie Duthe who was speaking extremely slow

 

Poor Duthe, says tradition,was so long pondered what to say to the that the  people around her thought that the mentally retarded, so her strange way of expressing the theme of a satirical show Les curiosités de la Foire, placed on the Paris boards 1775 year.
The comedy is alleged to be so ridiculous that the Parisians filled the hall for a weeks, and they soon became a habit make Duthe ridicule and all the ladies that are reminiscent of her.
