Ninjas keeping Sega employees quiet

What's the best way to keep people quiet? Mousey Mousey 1-2-3 is fine, but that only works on children and stupid people (doubly well on stupid children). Conan the Librarian's a good choice, obviously, but he's pretty pricey. No, we think Sega's got it all figured out. As you can see from the above picture recently taken by MTV Multiplayer in Sega's offices, they're keeping employees mum with inspirational ninja posters.

So, do the posters work? Well, let's put it this way: Either they're duds, or they're far, far away from the offices of people working on Sonic Unleashed, Samba de Amigo and the Platinum Games deal.
