Stewie's revenge

I was watching TV when Family Guy came on. When the opening of the episode started something was different about it the intro sounded demonic like something out of a horror movie. At the end of the opening there was an x over all the Griffin's except Stewie. The episode was the same as Daboom. I was confused why they would use the same episode but call it something different but I still went ahead and watched it. Things took a dark turn when Conjoined Cleveland and Quagmire came over to the Griffin's house Stewie first choked Cleveland then chokes Quagmire. All the Griffin's are freaking out about this and Stewie says in a demonic voice you can run but you can't hide. Stewie first found Meg and the screen went black for a few seconds then came back on and showed Meg lying there lifeless and cold. Stewie crossed an x over Meg and says 4 more to go. This continues until all the Griffin's are lying there lifeless and cold. Then Stewie turns to the camera and says you're next. I turned off my TV and never watched Family Guy after that.
