i Used to believe that all adult shows [even adult cartoons] were NOT supposed to be funny. They were supposed to be very serious. I knew that The Simpsons was an adult show, because my mom never let me watch it before. So then one day, she did. It was the first show i had seen that didn't have a laughtrack. i Also didn't understand any of the jokes so i thought it was very serious.
Also, i thought Beavis and Butthead were real, serious names. I had never seen the show, so i thought it was like Regis and Kelly or something! [which i also had never seen]
