I know it sounds a silly question, but I'll ask anyway.
The other day I had a discussion with some cybernauts about the phenomenal language of the librarian-"oook". Some insisted that it's the librarian's stammer (an improper pronunciation of "ok") which is very funny. But others thought it's the imitation of the sound the librarian made; otherwise it would be quite absurd according to the context. I concur with the latter view. As English isn't my mother tongue. I'd like someone to help me clarify this.
Thanks in advance!
