It's worth noting, especially in the context of the website in question, that one of Marcel Duchamp's more infamous dadaist works consisted of a cheap repro of the "Mona Lisa" with a handlebar mustache drawn on it and the letters "LHOOQ" written underneath. As for those letters, they're an anagram for a phrase that roughly translates "She's got a hot ass". Given the content of the LHOHQ stuff, its context, and such, there's definitely a linkage there.
