After watching the episode where a 300lb fat man thinks he is michael jackson my girlfriend and I cant figure out if it is really michaels voice. Iv looked around on google and what not and some places say it wasnt his voice cause he wasnt in the credits, others say it was his voice and he asked to be taken out of the credits and some say he did the voice but not the song.. soo not being a fan I cant tell the difference myself.. Does anyone know for sure what the real deal is?? The whole thing has got me curios now..
