It’s really, really hard to get the kernel of a story, and make that kernel have a punch… but it can be done.
“I can prove he’s lying” from the old Avatar cartoon comes to mind… but not much else.

But, if you can get the Big Surprise spot on, there’s no better feeling than really wowing a gaming group!
