What do you say to an angry witch?

This particular toy didn't even last one week.

One of the friends of the market's organisers took one look at this and insisted she needed to buy for a friend of hers and bought the first day I had it on the stall. My quickest sale ever!

And to answer the question in the title, according to a joke I read, the answer is "ribbit". I'll leave it up to the readers to figure out why :).
