I was reading Dawn and the Big Sleepover and found this:
Ms Besser said to Dawn: "Do me a favour.  Would you mind staying exactly the same age for a few years until I have a child old enough to be bay-sat for."

!!!

Well done Ms Besser.  If you ever get sick of Stoneybrook Elementary, there might be a job available for you at Hogwarts.
