Hangman

If you've ever fumbled in complete and utter darkness for the little chain that will turn on your light and thus reassure you that a serial killer is not lurking in your basement, then you will appreciate the genius of this little glow-in-the-dark dude.

And when you're shivering in bed at 2:00 AM but can't find the chain to turn off the damn ceiling fan, this guy can help you out. Unlike the guy who turned the fan on in the first place.
