Nope. That's a whole freshly opened can of nope. Forget that noise. You're pretty sure you don't live in a jungle. You step back out, close the door, and take a deep breath.

Curiosity gets the better of you, and you crack the door a little to peek inside again. This time, the scene has been replaced with a high-tech spaceport. You close the door for a moment and reopen it for another peek. You see rows of chimpanzees, perhaps millions of them or more, stretching out past the horizon. Each one is tapping away at a typewriter. You would probably be interested in reading some of what they've written, but you close the door again.

What are you going to do?
