The teacher, like all adults in the Peanut's series, didn't actually talk. In the comics, you just see the children looking up at something and responding as if spoken to: "Yes sir" and "I understand" and so on. In the TV series, the teacher made an odd, comical sound instead of talking, the closest representation in typing being along the lines of "Wah wah woh wah wah". As in the comic, the viewer was meant to wonder what the adults were saying by observing the kids' reactions.
