Hello, I'm trying to find the source of a plot fragment that may have come from an RB story:

A woman offers a small child a bag of jellybeans, telling the child to pick just one. The child takes one and just as he's about to eat it, she snatches the jellybean away and says "There! Now I have your soul!"

Any help tracking down the origin of this plot fragment would be greatly appreciated.

Thanks

Well, I can tell you it's not, but I can't say what it is from. There are three other forums on which I post these plots, where they are sometimes identified. No replies on this one so far.
