Holliday, Jayne Mansfield (dyed blonde), Carol Wayne and Goldie Hawn. Goldie Hawn is best known as the giggling "dumb blonde", stumbling over her lines, especially when she introduced Rowan & Martin's Laugh-In "News of the Future". In the American sitcom Three's Company the blonde girl (originally Chrissy, played by Suzanne Somers, and later Cindy and Terri) is sweet and naïve, while the brunette (Janet, played by Joyce DeWitt) is smart. Country music star Dolly Parton who recorded a song called "Dumb Blonde", famously said that dumb blonde jokes about her do not offend her because, "I know I am not dumb, and I am not blonde." Blonde jokes There is a category of jokes called "blonde jokes" that employs the dumb blonde stereotype. It overlaps at times with other jokes that portray the subject of the joke as promiscuous and/or stupid. Some blonde jokes rely on sexual humour to portray or stereotype their subjects as promiscuous. Many of these are rephrased sorority girl or Essex girl jokes, much as other jokes about dumb blondes are based on long-running ethnic jokes. Many of these jokes are mere variants on traditional ethnic jokes or jests about other identifiable groups (such as Italian jokes involving Carabinieri, Sardarji jokes or Pathan jokes). Similar jokes about stereotyped minorities have circulated since the seventeenth century with only the wording and targeted groups changed. Blonde jokes have been criticized as sexist by several authors, as most blondes in these jokes are female, although male variations also exist. In fact, dumb blonde jokes are overwhelmingly female-specific: according to an extensive search in various publications and on the Internet, about 63% of dumb blonde jokes are directed exclusively at females (compared to less than 5% that directly referenced dumb blond men). Research indicates that because of this, men report being amused by blonde jokes significantly more than women do. The fact that most of these jokes target the invariably dim-witted, and sexually promiscuous, female makes them even more sexist. In the 20th century, a class of meta-jokes about blondes (i.e. jokes about blonde jokes) has emerged. In a typical plot of this type, a blonde complains about the unfairness of the stereotype propagated by blonde jokes, with a punch line actually reinforcing the stereotype.
