Since this Trope page has no equivalent at the TV Tropes Wiki, it could really use more examples here. Off the top of my head, I can't think of any thing I've read or watched that made use of this as a trope or plot device, so I'm afraid I'm of no use in this regards. Could someone who's a little more familiar with the concept please fill this one in?
I also note that there are no links to this page from anywhere else. (You can test this by clicking "+ options" at the bottom of the page, and then "backlinks" on the menu that that creates.) Which means the only way someone will stumble across this page is if it comes up on the random page list (given 3400 other pages, that's not gonna happen too often) or this week while it's still on the short list of recent pages. Colonel, was there a specific page or topic that made this concept come to mind? If so, we should link here from there. If not, then we should at least figure out where it belongs on the big trope lists and link from them.
