For comical relief, a blur is shown over a Sim when s/he is using the shower or using the bathroom. The blur can be removed with a nude patch. The cheat code that once worked with "The Sims 2" and "The Sims 2 University" no longer works in "The Sims 2 Nightlife." You will have to download a patch if you want to use the nude patch with "The Sims 2 Nightlife."
