There is much debate over which characters in Family Guy can understand Stewie. In an interview, MacFarlane said that everyone can basically understand him, but they ignore him or just think to themselves ''oh how cute'' when he talks. However at the 2011 ComicCon panel, he compared this to Wile E. Coyote in the old Merrie Melodies cartoons. MacFarlane went on to say that Brian always hears Stewie, and more recently so does Chris, but the writers usually strive for Peter, Lois, and Meg not to hear him. Once Stewie leaves the house, the question of who can hear him depends very much on the story. MacFarlane also states that these rules can be broken for the sake of comedy, so this could change from one episode to another. In ''Inside Family Guy'', Peter apologizes to the family, to which Stewie comments: ''Oh that's nice of you to say''. Peter replies: ''Thank you, Stewie, who I can understand'', referring to the ongoing discussion whether or not family members, other than Brian, are able to understand him. However, Peter's response seems to be a part of the episode's offset setting, where everyone is out of character.
