Regarding this one: http://www.cucumis.org/traducerea_11_t/view-the-translation_v_49113.html - I was not looking for the word-by-word translation. For that I know enough Danish to do it by myself. I am looking for the Danish equivalent of the English saying: "the pot is calling the kettle black" which means that you laugh about something wrong that someone did when actually you have done the same stupid thing.
