Most school children in the US read the Diary of Anne Frank in history class at some point in their education. The book, which is the recovered diary of a teenage girl who was forced into hiding during the Holocaust, has been a great way to connect kids to the reality of what Jews, Blacks, Catholics, homosexual people, and Gypsies suffered at the hands of the NAZIs. However, researchers are now revealing that the version you read in school is missing a couple of pages.

The two newly uncovered pages, from September 28, 1942, include jokes and thoughts from the teen about sex, prostitution, birth control, and homosexuality.

While we don’t have the direct translation, TMZ has summed it up as follows:

The humor’s a little lost in translation, but one is about German soldiers banging Dutch women, and others are about men catching their wives banging other men … and men with ugly wives.

About prostitution, Anne wrote: “All men, if they are normal, go with women, women like that accost them on the street and then they go together. In Paris, they have big houses for that. Papa has been there.”

She also described a young woman getting her period around age 14 as “a sign that she is ripe to have relations with a man but one doesn’t do that of course before one is married.”

It turns out that the pages had never been seen because Anne had covered them over with brown paper and glue so that no one else would read them. It took a combination of backlighting the pages and utilizing image processing software to uncover her words.
