content: I picked up the dirty old thumbed copy from a salvalion army op shop for 30 cents. It looked like all the pages were bent but they had been carfully turned over to mark some of the jokes many years before. I started reading. It was not just a collection of jokes but a beautifully researched and systematic approach. It is to jokes what the oxford dictionary is to the language. It suprising the change since it was written as amongst my friends many of the jokes are not well known and clearly others have technological adaptation. the suprising issue is how things have changed culturally since it was written. One wonders if menstral jokes for example are shared within lesbian social groups that would be taboo in other company or if the degree of ethnic jokes that are no longer promulgated in polite company have their early source listed here. If the porice was right I would like copies for my friends
