Hehe sry forgot to mention the voices part. Basically all we do is film ourselves talking and then we cut out the video so that we only use the audio part. I then edit them in premiere, changing pitch and whatnots. I just tinker with it until it's good enough

I can get alot of voices doing this with only 2 people lol. All i have to do after that is combine it with the Episode and there you have it!
