Creepy voice origins

I'm a big Family Guy fan, and today I made an unexpected discovery on Family Guy's IMDb trivia page:

Seth Green reveals in the commentary on Family Guy Presents: Stewie Griffin - The Untold Story (2005) (V) that the voice of Chris is based on Ted Levine's performance as Buffalo Bill in The Silence of the Lambs (1991).

Hmm . . . I never got the impression that Chris Griffin sounded much like Buffalo Bill. Nor can I picture Chris Griffin uttering, "It rubs the lotion on its skin, or else it gets the hose again!" Really, that's more a drunken Peter Griffin utterance.
