Seth Green is actually responsible for doing the voice work for two characters on the show Family Guy. First, he voices the son main family's son, Chris Griffin. Then he also is Neil Goldman, the nerd with a crush on Meg Griffin. Seth has admitted that he used the character Buffalo Bill from the movie The Silence Of The Lambs when he auditioned for the job with The Family Guy. He said he just protrayed what he thought Buffalo Bill's voice would sound like if he was talking through the speaker at a drive up fast food place!
