As the title of Samantha Ball's "...!" would suggest, there's a twist ending. In fact, unlike last week's short story choice in which the story would have held up without the twist at the end, "...!" depends on the twist in order for it to work. Therefore it's impossible to discuss the story without spoiling the whole shebang. So, if you think you might want to read it for yourself, I'd suggest doing so now before reading any further.
"...!" is amusing, but doesn't feel fleshed out enough. It's more like a joke, or actually, more like a commercial. Still, it's got one of those 6th Sense sort of endings, where you just have to go back and read it again now that you know the secret, to make sure it still makes sense. Fortunately, it's short enough to do so, and it does work.
