remember...

... the ending of "A Nightmare on Elm Street," when everything's seemingly OK and the mom is waving goodbye on the front porch, and Freddy's arm breaks through the front door's glass pane, grabs the mom and sucks her through an impossibly small opening?

It would be cool to be able to do that in real life. Especially at work, when you walk by somebody's office and the door is closed and they're listening to smooth jazz very loudly in there, and you bet they're all cool and relaxed.

I bet they wouldn't see that coming.
